Need the equation for this:

in 2015, jeralyn a choice between buying a fonda concord ex for 40,000 which depreciates (decreases) at 5% per year.

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

Solve by any method (graphing, substitution or linear combination)y = x - 82x + 3y = 1a) (2, -6)b) (5, -3)c) (4, -4)d) (0, -8)i figured it out. the answer is (5, -3)

Which is the equation of a line perpendicular to the line with the equation 3x+4y=8
