To get the new points for dilation with a scale factor of 1.5, we multiply 1.5 times (x,y) the ordinated pairs of each of the vertex of the triangle.
A'
[tex](1.5\times-4,1.5\times-2)=(-6,-3)[/tex]
B'
[tex](1.5\times-2,1.5\times4)=(-3,6)[/tex]
C'
[tex](1.5\times4,1.5\times-2)=(6,-3)[/tex]
The algebraic expression is:
[tex](x,y)=(1.5x,1.5y)[/tex]
