Answer:
1. slope m = -2
2. slope m = 4/3
Explanation:
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
Hope this helps :)
