Question

How to write (-4,5) and (0,-4) in y=mx+b

Answer 1

Answer:

y = 9/5 x -4

Step-by-step explanation:

first find slope or m

slope is change in y over the change in x

-4-5/0-5 =-9/-5 = 9/5

the (0, -4) is the y intercept or b

Answer 2

Answer:

Step-by-step explanation:

(-4,5) and (0,-4)

y2 = -4, y1 = 5, x2 = 0 and x1 = -4

slope m = {y2-y1}/{x2-x1}

m = {-4 - 5}/{0 + 4}

m = -9/4

And

y - y1 = m(x - x1)

y - 5 = -9/4(x + 4)

y - 5 = -9x/4 - 9

y = -9x/4 - 9 + 5

y = -9x/4 - 4
