Find the slope of the storage shed's roof.

• The slope is 3/15 = 1/5.

• The slope is 5/15 = 1/3.

• The slope is 3/5 = 3/5.

• The slope is 1/3 = 3/9.

Find the slope of the line.

• The slope is (2-0)/(2-0) = 2/2 = 1.

• The slope is (2-0)/(0-2) = 2/(-2) = -1.

• The slope is (0-2)/(2-0) = -2/2 = -1.

• The slope is (0-2)/(0-2) = -2/-2 = 1.

Find the slope of the line represented by the table below. (Examples 2 and 3)

• The slope is (3-1)/(1-0) = 2/1 = 2.

• The slope is (3-1)/(1-0) = 1/2 = 0.5.

• The slope is (3-1)/(1-0) = 1/1 = 1.

• The slope is (3-1)/(1-0) = 3/2 = 1.5.

Find the slope of the line that passes through each pair of points. (Example 4) A(-3, -2), B(5, 4)

• The slope is (4 - (-2)) / (5 - (-3)) = 6/8 = 3/4.

• The slope is (4 - (-2)) / (5 - (-3)) = 2/8 = 1/4.

• The slope is (4 - (-2)) / (5 - (-3)) = 8/6 = 4/3.

• The slope is (4 - (-2)) / (5 - (-3)) = -6/8 = -3/4.

Find the slope of the line that passes through each pair of points. (Example 4) E(-6, 5), F(3, -3)

• The slope is (-3 - 5) / (3 - (-6)) = (-8)/9 = -8/9.

• The slope is (5 - (-3)) / (-6 - 3) = (8)/(-9) = -8/9.

• The slope is (5 - (-3)) / (3 - (-6)) = (8)/9 = 8/9.

• The slope is (-3 - 5) / (-6 - 3) = (-8)/(-9) = 8/9.

In any linear relationship, the slope is always the same because:

• the rate of change between variables remains constant.

• the y-intercept changes for every point.

• the variables are always increasing.

• the line curves at different points.

• 15/24 or 5/8

• -24/15 or -8/5

• 24/15 or 8/5
