What is the equation for the line?

The equation of the line will be in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

Let us first find the slope using the coordinates (0, 5) and (-2, 13) with y1 - y2/x1 - x2:

5 - 13 / 0 - (-2)
-8 / 0 + 2
-8 / 2
-4

The slope is -4. To find the y-intercept, look at the graph to see where the line intersects the y-axis. It appears to be at (0, 5); the y-intercept is 5.

y = -4x + 5
