Polygon ABCDE is dilated by a scale factor of 3 with the center of dilation at the origin to create polygon A′B′C′D′E′. If the endpoints of BC are B(3, 5) and C(5, 10), what is the slope of B'C' ?

The fact it is dilated makes no difference to the slope of BC to B'C'

Using the regular slope laws (y2-y1)/(x2-x1), you find out the slope is 5/2
