A graph is shown below:



What is the equation of the line in slope-intercept form? (5 points)


y = –2x + 8

y = –8x + 2

y = –2x + 16

y = 16x – 2

Answer 1

y = -2x +16

Explanation:

I just did the test.

Answer 2

We know the y intercept is 16 because y=16 when x=0.

Find slope by calculating change in y over change in x.
(12-16)/(2-0)
-4/2
-2

Plug both values into slope intercept form. y=mx+b where m is slope and b is the y intercept.

Final answer: y=-2x+16
