The discount is $7, and Mrs.Hill only has to pay $28.
Answer:
y-2=2/3(x+1) OR y=2/3x+8/3
Step-by-step explanation:
y=2/3x-2 (2/3 represents your slope)
plug into this equation y-y1=m(x-x1) (m represents your slope, y1 and x1 are you points)
so y-2=2/3(x+1) OR y=2/3x+8/3 (move the -2 over, distribute the 2/3 to (x+1) and then add 2/3 to the 2 you moved over)
