Question

Here’s a graph of a linear function. Write the equation that describes that function. Express it in slope-intercept form.

Answer 1

y=1/3x-3

Explanation:

slope = (y2-y1)/(x2-x1)

Use the two points: (0,-3) (3,-2)

slope = (-3+2)/(0-3)

slope = -1/-3 = 1/3

y intercept = -3

Equation: y=1/3x-3
