Lines p and q are perpendicular. if the slope of line p is 2, what is the slope of line q?

a.
b. -
c. -2
d. 2

For this case we define the following variables:

By definition, since the lines are perpendicular, it follows that:

Substituting values we have:

From here, we clear the value of the slope of the line q:

The slope of line is:

hello! just here for points! though i wish i knew!

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
