Find the equation of the line through the points (-4,6) and (1,-9). Write your answer in the form
y = mx + b.

Answer 1

Answer: y = -5x - 14

Explanation:

first find the difference between the x variables x1 = 1 and x2=-4 to find the slope(m)

-4 - 1 = -5

next find the difference between the y variables to find b

-9 - 6 = -14

Answer 2

m=Y2–Y1/X2–X1

`m = ( - 9 - (6))/(1 - ( - 4)) \\ m = ( - 15)/(5) = - 3 \\ y = mx + b \\ y = - 3x + b`
