Question

for this one i guessed that the slope intercept is y=8x+0 am i right

Answer 1

Your x-intercept is (7,0). Plot this point. Rewrite "slope = 8" as "slope = (8/1).

Starting at (7,0), move 1 division on the x-axis to the right and then from there move 8 units up. Plot this point. Draw a line thru the 2 points.

Answer 2

its not asking me to graph

Answer 3

and its y=7x+0 is that right?

Answer 4

Nope. In the slope intercept form: y = mx + b, b is the y-intercept, not the x-intercept.

Answer 5

then its y=8x+0?

Answer 6

The slope is given as 8 means m=8, right?

Answer 7

yes

Answer 8

oops y=8x+7?

Answer 9

So now use the form y=m+b and fill in what you know.

Answer 10

i said y=8x+7?

Answer 11

You do not know the 7 yet.

Answer 12

how do i do it in y=mx+b

Answer 13

y = 8x + b

Answer 14

its not 0 or 7 :(

Answer 15

@skullpatrol

Answer 16

The point (7, 0) is on the line, right?

Answer 17

yes

Answer 18

Replace x with 7 and y with 0 in the equation y = 8x+b, then solve for b

Answer 19

0=56x+b??

Answer 20

Almost! Why 56x

Answer 21

No b=-56. x is gone because you plugged 7 in for x

Answer 22

So when you plug that back into the original equation you get y=8x-56

Answer 23

Could you let the student do the learning. Please.

Answer 24

how is it in standard form>? i know standard is Ax+By=c

Answer 25

I'm sorry):

Answer 26

how do i write it in standard form @skullpatrol @GiannaBaroni

Answer 27

Any ideas?

Answer 28

hmm i think 7x+8y=0?

Answer 29

Why?

Answer 30

$$\Huge y=8x-56$$

Answer 31

You want the form ax + by = c.

Answer 32

8x+56y=7

Answer 33

How did you get 56y?

Answer 34

Subtract 8x from both sides of y = 8x - 56 please :-)

Answer 35

i get 48 if i subtract 56-8 oopes i mean -48

Answer 36

Try again

Answer 37

-64?

Answer 38

$$\Huge y=8x-56$$

$$\Huge y-8x=8x-56-8x$$

$$\Huge y-8x=-56$$

Answer 39

Does that^ make sense?

Answer 40

yes it makes sense so far

Answer 41

The last step is to write it as -8x + y = -56
