Lol i'm doing a maths test. last question can someone help me :)

Part a : solve -vp + 40 < 65 for v part b : solve 7w - 3r = 15 for r show your work .

Secant ac and bd intersect at point e inside f what is the measure of aed if measurements cd equals 30 a b is 50 and cb is 170

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.
