A city planner wants to build a road perpendicular to D Street. What is the slope of the new road?
Accepted Solution
A:
Answer:The slope of the new road is 0.Step-by-step explanation:the slope of d street line is tan(90)[if the angle made by a line with x axis is [tex]\alpha[/tex] then, the slope of that line will be tan([tex]\alpha[/tex]) ]here, the angle made by the d street line with x axis is 90 degrees.if a road is to be built which is perpendicular to d street , it should make 0 degrees i.e, it should be parallel to x axis .so, the slope of new road will be tan(0) = 0
