The coordinates of point A are 30 units of X and 26 units of Y.The coordinates of point B are 22 units of X and 30 units of Y.With X on the horizontal axis and Y on the vertical axis,the slope of the line between points A and B is
A) + 2.00
B) + 0.50
C) + 0.33
D) - 2.00
E) - 0.50

Quizplus · Accepted Answer

The slope of a line passing through two points can be calculated as:
slope = (change in y)/(change in x)

Therefore, the slope of the line passing through points A (30, 26) and B (22, 30) can be calculated as:

slope = (30 - 26)/(22 - 30) = 4/-8 = -0.5

Thus, the slope of the line passing through points A and B is -0.5, which corresponds to choice E.

The Coordinates of Point a Are 30 Units of X
