6 questions in the course bank use Rise, in Slope & Unit Rate.
Problem 1
Find the slope through (1, 2) and (5, 10).
Worked answer
2
Rise: 10 - 2 = 8
Run: 5 - 1 = 4
m = 84 = 2
Problem 2
Find the slope through (0, 3) and (4, 9).
Worked answer
3/2
Rise: 9 - 3 = 6
Run: 4 - 0 = 4
m = 64 = 32
Problem 3
Find the slope through (2, 8) and (6, 2).
Worked answer
-3/2
Rise: 2 - 8 = -6
Run: 6 - 2 = 4
m = -64 = -32
Problem 4
What is the slope of the line y = -4?
Worked answer
0
Every point has y = -4
Rise is 0
m = 0
Problem 5
Find the slope through (-3, 5) and (1, -7).
Worked answer
-3
Rise: -7 - 5 = -12
Run: 1 - (-3) = 4
m = -3
Problem 6
A line passes through (2, 5) and falls 3 units for every 4 units right. Find the slope.
Worked answer
-3/4
Rise = -3, run = 4
m = -34
