Explanation:
AB is one unit corresponding line AK is five units scale factor of k = 5
Center of dilation: ( pick two corresponding points: -2,2 and -6,6 )
and use the formula:
x: ( kx1-x2)/(k-1) = ( 5(-2) - -6) / (5-1) = - 4/4 = -1
y: ( ky1 - y2) /(k-1) = (5(2) -6) / ( 5-1) = 4/4 = 1
centered at (-1,1) ( the common vertex of the two)
