Question

Find the slope of the line

(Please don't answer if you don't know it. It doesn't help at all.)

Answer 1

The slope is -3. Pick any point on the line. For every 1 unit you move to the right, the "next" point on the line is 3 units down.

You can also use the formula for the slope. According to the graph, the line goes through the points, say, (1, -3) and (3, -9). Then the slope is

slope = (-9 - (-3)) / (3 - 1) = (-9 + 3) / (3 - 1) = -6/2 = -3
