Question

help?

Answer 1

slope is 8

Answer 2

Deal with your parenthesis first then make sure you have your y variable alone on it's own side
Then combine like terms - if necessary
Make sure it is in slope intercept form: y = mx + b

Answer 3

What is x?

Answer 4

Finding the slope in an equation like this you would have to use the formula y=mx+b

Answer 5

You would have to plot in the equation that you have into it.

Answer 6

So first things first, you have parenthesis so you need to distribute.
y-7=8(x-14)
Distribute the 8 to x and -14

Answer 7

so 8x-14?

Answer 8

No, what's 8 × -14?

Answer 9

You forgot to distribute 8 to -14

Answer 10

You only distributed the 8 to x which is how you got 8x. But remember there are 2 terms inside the parenthesis. Whatever is inside you have to multiply with the # outside of it

Answer 11

So 8 x -14 should give you -112
Now your equation should look like this: y - 7 = 8x -112

Answer 12

so your equation is y-7 =8(x-14)
and the equation you have to use is y=mx+b
in the equation you would have to use is the m equals the slope and the b would be the y-intercept.
In this case you won't have to solve for anything because the slope is already in your equation. as I said m=slope and the m in your equation is 8 so, you don't have to solve for anything.

Answer 13

How did that just turn into -112?

Answer 14

-112*

Answer 15

so i do nothing with the x?

Answer 16

Nope you'll leave it

Answer 17

so the x is multiplication ?

Answer 18

But were not done yet
Y has to be by itself so we need to add 7 to -7 to cancel it out
Whatever you do to one side you do to the other yada yada yada...
And it should look like y=8x-105

Answer 19

but you just times it tho?

Answer 20

Times what?

Answer 21

You were only multiplying because you were distributing that's how we got 8x and -112

Answer 22

distributing? whats that?

Answer 23

Oh my

Answer 24

Distributing is when you equally give out the same quantity to each number. For example: I have 3 cookies and I have 6 friends. I distribute the cookie to each friend so that way each person gets the same amount... get it? ;-,

Answer 25

so i cut the cookie in half?

Answer 26

Egzaclee

Answer 27

You equally give each friend the right amount if cookie

Answer 28

Kinda like what we did with the 8. We distributed it to every number inside the parenthesis. When you distribute your multiplying

Answer 29

But the parenthesis if i cut it in half it becomes 7?

Answer 30

Where did u get 7?

Answer 31

Ok honestly it doesn't matter
The slope is literally the number attached to x
What number is attached to x???

Answer 32

8?

Answer 33

Yes child

Answer 34

but how do we know if its attached to 14? or 8?

Answer 35

Your distributing 8 not 14. The number outside the parenthesis is what your "sharing" to every number inside it

Answer 36

So your sharing 8 with x and 8 with -14

Answer 37

Oh so no matter what, whatever number is the parenthesis is never distributed?

Answer 38

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : y-7-(8*(x-14))=0

(y - 7) - 8 • (x - 14) = 0

y - 8x + 105 = 0



Solve y-8x+105 = 0

we have here an equation of a straight line. Such an equation is usually written y=mx+b

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-8x+105 = 0 and calculate its properties

Notice that when x = 0 the value of y is -105/1 so this line "cuts" the y axis at y=-105.00000

y-intercept = -105/1 = -105.00000


When y = 0 the value of x is 105/8 Our line therefore "cuts" the x axis at x=13.12500

x-intercept = 105/8 = 13.12500




Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -105.000 and for x=2.000, the value of y is -89.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -89.000 - (-105.000) = 16.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = 16.000/2.000 = 8.000


The slope is (8)

Answer 39

(y - 7) - 8 • (x - 14) = 0

y - 8x + 105 = 0
So 14-(y-7)-6x=0?

Answer 40

What? No the second one is correct but make sure that "-" is a "="

Answer 41

But yes your slope would be 8 because it is the number attached to your variable "x"
Your slope is also known as m
y = m x + b

Answer 42

I solved it

Answer 43

It was already solved he just got confused

Answer 44

Got ya

Answer 45

Do you have anymore questions?

Answer 46

@tetsxpreme

Answer 47

Nice job answering the question, jay and depp but to simply put it, you could of answered this question without doing any math. In algebra, you need to know your formulas. And this equation was in `point slope form.`

\[y - y _{1} ~ = m(x-x _{1})\]

you already know that m is the `slope` so what ever the `m-value` is, in the question, would be your slope :)

Answer 48

Thank you so much guys
