The slope of a line often referred to as the (
(rise)/(run)) is the rate of change in a line. It can be found using the following formula.


(y_2-y_1)/(x_2-x_1)

Where (
x_1,y_1) and (
x_2,y_2) are points on the line. For each problem, substitute the points on the line into the formula and solve for the slope.

1.
(1)/(2)

(0, 2), (-2, 1)


=(1-2)/(-2-0)\\\\=(-1)/(-2)\\\\=(1)/(2)

2. 2

(-2, -1), (0, 3)


=(3-(-1))/(0-(-2))\\\\=(3+1)/(0+2)\\\\=(4)/(2)\\\\=2

3. 4

(1, 0), (2, 4)


=(4-0)/(2-1)\\\\=(4)/(1)\\\\=4

4. 1

(6, 2), (2, -2)


=(-2-2)/(2-6)\\\\=(-4)/(-4)\\\\=1

5.
(3)/(5)

(-1, 1), (4, 4)


=(4-1)/(4-(-1))\\\\=(3)/(4+1)\\\\=(3)/(5)

6.
(1)/(3)

(-7, 4), (2, 1)


=(4 -1)/(2-(-7))\\\\=(3)/(2+7)\\\\=(3)/(9)\\\\=(1)/(3)

7. 0

(5, -3), (-2, -3)


=(-3-(-3))/(-2-5)\\\\=(-3+3)/(-7)\\\\=0

8.
(7)/(5)

(-3, 2), (2, 7)


=(7-2)/(2 - (-3))\\\\=(7)/(2+3)\\\\=(7)/(5)

9. 8

(2, 16), (3, 24)


=(24-16)/(3-2)\\\\=(8)/(1)\\\\=8
