We have the following:
the point are:
[tex]\begin{gathered} A=(-4,-2) \\ B=(-2,4) \\ C=(4,-2) \end{gathered}[/tex]After applying the scale factor it would be
[tex]\begin{gathered} A^{\prime}=(-4\cdot1.5,-2\cdot1.5)=(-6,-3) \\ B^{\prime}=(-2\cdot1.5,4\cdot1.5)=(-3,6) \\ C^{\prime}=(4\cdot1.5,-2\cdot1.5)=(6,-3) \end{gathered}[/tex]A' = (-6, -3)
B' = (-3, 6)
C' = (6, -3)
Algebraic Representation:
[tex]\begin{gathered} A^{\prime}=1.5\cdot A \\ B^{\prime}=1.5\cdot B \\ C^{\prime}=1.5\cdot C \end{gathered}[/tex]
