Question

Find the equation of the linear function represented by the table below in slope-intercept form.

Answer 1

First find slope: (y2-y1)/(x2-x1)
pick 2 points: (-3,9), (1,-7)
(-7-9)/(1+3) = -16/4 = -4
Slope intercept form: y = mx + b
y = -4x + b, plug in a point
9 = -4(-3) + b
9 = 12 + b, b = -3
Equation: y = -4x -3
