Kevin bought a used guitar at a garage sale for $150. He fixes it up and sold it for $200. What was the percent increase?

Without graphing the linear functions, find the coordinates of the point of intersection of their graphs: y=3x−11 and y=4

Given: x + y = 6. if xe (-15, -6, -1), then which of the following sets of ordered pairs are solutions? © {(-15, -21), (-6, -12), (-1, -7)} [(-15, 21), (-6, , 7)} {(-15, 21), (-6, 12), (-1, -7)}

15 point ! ~ see if you know the answer to both you!
