I might as well make an account, since I need so much help! Sorry, I just need to figure this stuff out!
Draw the dilation with a scale factor of 1.5. Remember that to dilate something in the coordinate plane, multiply each coordinate by the scale factor.
To find the cale factor....we just need to compare the lengths of similar sides of Figure 2 and Figure 1
Look at the base of Figure 2..its length = 2
Look at the base of Figure 1.....its length = 4
So....the scale factor is
Length of base of Figure 2 2 1
_______________________ = _____ = _____
Length of base of figure 1 4 2
i agree that you just need to compare the lengths of similar sides of Figure 2 and Figure 1
