Question

Hi guys! i have a question about slope intercept form. So I have these coordinates (-8,4) and (-8,2)
If I did the math right, the slope should be 0. how do u right this all in slope intercept form. I'm not really sure where to start so if you help me I will become fan and give out a medal! thanks in advance!

Answer 1

can you help me @Owlcoffee

Answer 2

Yes, i was thinking how I could explain it.

Answer 3

alright ill wait(:

Answer 4

also if you could put it into standard form it would really help!!

Answer 5

y = whatever b is.

Answer 6

???

Answer 7

could you explain it?

Answer 8

Also can you tell me the standard form and the x and y intercepts

Answer 9

So we have the points, let's call them A and B, where A(-8,4) and B(-8,2).
We'll begin by looking at the slope formula, applied to the points in question:
\[m=\frac{ y _{b}-y _{a} }{ x _{b}-x _{a} }\]
So, you say that replacing the points we get a slope of 0, and let's take a look at the formula that allows us to determine the line equation having a pointand the slope:
\[(y-y _{1})=m(x-x _{1})\]
I'll take point A, and replace it:
\[(y-4)=0(x+8)\]
\[(y-4)=0\]
\[y=4\]
Now, let's look at the point-slope formula:
\[y=mx+b\]
but you said that the slope is 0, and that's true, so we have a formula in the form of:
\[y=b\]
That means that the line, is parallel to the x-axis, like this:

Answer 10

the standard form is x + y= 4

Answer 11

What about the intercepts?

Answer 12

working on it

Answer 13

0 for the x intercept and 4 for the y

Answer 14

if the slope is 0, then there is no x intercept.
The formula isn't y=x+b because then you'll presuming that the slope is 1.
And that's not true.

Answer 15

oops! i meant y = 4

Answer 16

The standard or general form of it is y-4=0

Answer 17

sorry what? just to clarify what are the intercepts, the slope intercept form and the standard form?

Answer 18

slope = (2 - 4) / (-8 - (-8)
slope = -2/0

If the 0 is in the denominator, then it is undefined slope, not 0 slope
slope intercept form is : x = -8

Answer 19

slope intercept form is y=4, standard is y+4=0, there is no x intercept, and y intercept is 4

Answer 20

Oh dear...

Answer 21

THANK YOU EVERYONE!!!

Answer 22

answer is x = -8
