The fabric costs $8.95 per yard.
Y = 5x + 3
when x = 4
y = 5(4) + 3 = 23
Answer (4,23)
For 90° clockwise rotation, (x, y) becomes (y, -x).
Your rotated point is (2, 3).
M = 57+46
(Since she has 46 less then martha, you know to find how many martha has you have to add 46!)
M=103
So martha has 103 coins!
