The slope of each line is calculated as: 1. m = 2; 2. m = 5/4; 3. m = 7/5; 4. m = -7/4; 5. m = 3/5; 6. m = -1/4; 7. m = 3; 8. m = -1/2; 9. m = 1/6.
How to find the slope of a line?
For any given line, the slope can simplify be calculated by finding the ratio of its rise to its run between any two points on the line. In other words:
Slope (m) = rise/run = change in y / change in x.
An upward slope will yield a positive value while a downward slope will yield a value that is negative.
1. Slope (m) = rise/run = 4 units / 2 units
m = 2
2. Slope (m) = rise/run = -5 units / 4 units
m = 5/4
3. Slope (m) = rise/run = 7 units / 5 units
m = 7/5
4. Slope (m) = rise/run = -7 units / 4 units
m = -7/4
5. Slope (m) = rise/run = 3 units / 5 units
m = 3/5
6. Slope (m) = rise/run = - 2 units / 8 units
m = -1/4
7. Slope (m) = rise/run = 6 units / 2 units
m = 3
8. Slope (m) = rise/run = - 2 units / 4 units
m = -1/2
9. Slope (m) = rise/run = 1 units / 6 units
m = 1/6.
