Graph the image of the figure after a dilation with a scale factor of 2 centered at (−7, −2) .
Use the Polygon tool to graph the quadrilateral by connecting all its vertices.
+128406 Formula
New Point = [ old point - dilation center ] * scale factor + dilation center
So
For (-1, 1)
[ (-1, 1) - (-7, -2) ] * 2 + (-7, -2) = [ 6, 3] *2 + (-7, -2) = [ 12, 6] + (-7, -2) = (5, 4)
For (-3, -2)
[ (-3, -2) - (-7, -2) ] *2 + (-7, -2) = [ 4, 0]*2 + (-7, -2) = [ 8, 0 ] + (-7, -2) = (1, -2)
For (-4, 3)
[ (-4,3) - (-7 , -2) ]*2 + (-7, -2) = [ 3, 5]*2 + (-7, -2) = [ 6, 10] + (-7, -2) = (-1, 8)
For (-6, 2)
[ (-6, 2) - (-7, -2) ] *2 + (-7, -2) = [ 1, 4]*2 + (-7, -2) = [ 2, 8] + (-7, -2) = (-5, 6)
