Someone help asap. please

Answer 1

y = -4x + 9

Explanation:

y = mx + b

First, we will find 'm', aka slope,

(
`y_(2)` -
`y_(1)`) / (
`x_(2)` -
`x_(1)`) = m

(-7 -5)/ (2 - (-1)) = m

-12/ 3 = m

∴ m = -4

Then we can substitute m = -4 and point 1 in y = mx + b to find 'b', aka y-intercept,

5 = -4 (-1) + b

5 = -4 + b

5 + 4 = b

∴ b = 9

Hence the equation is,

y = -4x + 9

Answer 2

Answer:Slope intercept form=(y-y1)=m(x-x1) where m is slope

y-5=5-(-7)/-1-2(x-(-1) (m=y-y1/x-x1)

y-5=-4(x+1)
