Question

Write the equation of the line given by the following graph in slope-intercept form.

y = –2x + 86

y = –2x – 10

y = –2x – 8

y = –2x + 10

Answer 1

y = –2x – 8

Answer 2

coz x intercept is -4

Answer 3

trailer is right

Answer 4

The slope is -2(change in y over change in x)
To calculate the y-intercept, we'll have to substitute any of the given co-ordinates.

-4 = -2(0) + b
-4 = b
So the y-intercept is -4.

That leaves the third one.
