Question

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

A) y = 2x + 8

B) y = -8x + 2

C) y = -2 + 16

D) y = 16x - 2

Answer 1

y = -2x+16

Explanation:

The line has a y intercept at 16 (This is where it crosses the y axis)

The slope is found by using

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

We have two point (0,16) and (8,0)

m = (0-16)/ (8-0)

= -16/8

= -2

We can use the slope intercept form of a line

y= mx+b where m is the slope and b is the y intercept

y = -2x+16
