Answer:
A' (11, 4), B' (-10, -6), C' (7, -9)
Step-by-step explanation:
Since you are reflecting over the y-axis, you take the opposite of the x value. So if the x is positive, make it negative. If the x is negative, make it positive. The y coordinate stays the same.
It helps you know what to multiply and the product when you subtracting and adding fractions.
The equivalent fractions are 3/4 & 12/16 hope this helps!!
