(10x-2y)+(-3y)= 10x-5y
(10x-5y)-(2x-2y)= 8x-3y
ANSWER: 8x-3y
JKLM to WXYZ
JM = 9 ZW = 13.5
JK = 12 WX = 18
the scale factor is what u multiply the original shape to get the coordinates of the other shape.
13.5 / 9 = 1.5
9 * 1.5 = 13.5
12 * 1.5 = 18
so ur scale factor is 1.5 (because if u multiply 1.5 by the original shape, u get the new shape)
