Question

Find the equation in standard form which passes through (3, –6) and (–2, –1). You must show all work.

Answer 1

standard form is:
y-y1 = M(x-x1)
So find M first.

Answer 2

M = (y-y1)/(x-x1)

Answer 3

m=-1?

Answer 6

You got the slope right. Now pick any of the two points, and use them as your (x1, y1) in this formula:

y-y1 = M(x-x1)

Answer 7

I got y=-x-3. Is that correct? @bahrom7893

Answer 8

Which point did you use?

Answer 9

If I use the second point:
y-(-1) = -1(x-(-2))
y+1 = -(x+2)
y+1 = -x-2
y = -x-3

Answer 10

Correct. Any point you pick will give you the same answer btw.

Answer 11

Okay Thank you
