Question

Can someone please help me? i need help so bad

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 -7)/ (4 - (-3)) = m

-14/ 7 = m

∴ m = -2

Then we can substitute m = -2 and point 1 in to find 'b', aka y-intercept,

7 = -2 (-3) + b

7 = 6 + b

7 - 6 = b

∴ b = 1

Hence the equation is,

y = -2x + 1
