Question

Write a linear equation for the line represented by the table above.

Answer 1

Answer: y = -x - 9
——————————————————————
Pick two points: (-2,-7),(-1,-8)
——————————————————————
Find a slope: m = ((-8)-(-7))/((-1)-(-2)) = -1/1 = -1
——————————————————————
Plug-in in to linear equation: y = mx + b
-8 = -1(-1) + b
-8 = 1 + b
-9 = b
—————————————————————
So… y = -x - 9
