Lines p and q are perpendicuar if the slope of line p is 2 what is the slope of line q

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?

Describe the end behavior of the function below. f(x)=(2/3)^x-2 a. as x increases, f(x) approaches infinity. b. as x decreases, f(x) approaches 2. c. as x increases, f(x) approaches -2. d. as x decreases, f(x) approaches negative infinity.
