What is the slope-intercept equation of the line below? A. y=-2x-3
B. y= 2x-3
C. y= 2x+3
D. y-2x+ 3

Hi there.

The answer is B choice.

Explanation:

Find the slope by using rise over run. As rise goes up 2 and run goes 1.

Thus 2/1 = 2.

Then find the y-intercept.

From y = mx+b where m = slope and b = y-intercept.

Thus the y-intercept is (0,-3) as shown in the graph.
