A motorboat moves across a lake at a constant speed. When it begins, it is 48 km from the shore. After 10 minutes, it is 18 km from the shore. Which
function describes the motorboat's distance from the shore?
A. y=-3x + 48
B. y = -10x + 48
C. y = 3x + 48
D. y = 10x + 48

Can someone me do math because i am having a breakdown rn because i don’t get it

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
