Question

for items 14–15, use the part of a city map shown. a city planner wants to build a road perpendicular to d street. what is the slope of the new road? slope =

Explanation:

Step1: Determine slope of D - Street

D - Street is a vertical line. The equation of a vertical line has an undefined slope. For a vertical line, the x - values are constant.

Step2: Recall slope relationship of perpendicular lines

If two lines are perpendicular, the product of their slopes is - 1. A line perpendicular to a vertical line is a horizontal line. The slope of a horizontal line is 0.

Answer:

0
