A:

1.

Use the two points given in the graph, and plug them into the slope formula.

slope = m = (y2, y1)/(x2 - x1)

slope = m = (3 - 1)/(0 - 1) = 2/(-1) = -2

Another way of calculating the slope is

slope = m = rise/run

slope = m = -2/1 = -2

As you can see, both methods give you the same answer.

2.

Here you have again two given points, so use the formula.

slope = m = (-3 - 1)/(-2 - 1) = -4/(-3) = 4/3
