Question

A graph is shown below:

What is the equation of the line in slope-intercept form?

y = −4x + 64
y = 64x − 4
y = −4x + 16
y = −16x + 4

Answer 1

y = -4x + 64.

Explanation:

The slope is rise / run = (64-0) / (0-16)

= 64 / -16

= -4.

The y-intercept is y = 64 so the equation is

y = -4x + 64.
