The new points will be A' (-6,9) B'(-6,-3)C'(6,-3) then graph them. REMEMBER: if the scale factor is greater than 1 the image will shrink. If the scale factor is less than one the image will enlarge
9x=5x+ (9=x)
(combine like terms)
9x=6x+9
(get the x value alone on one side of the equation, in this case by subtracting 6x from both sides)
3x=9
(divide by 3 on both sides to get x alone)
x=3
It is 16.50 because 9 divided by 6 is 1.5. so 1.5 is the unit rate. 1.5 x 11 = 16.5
