the formula to calculate the distance between two points is equal to
we have
O (0,0) and B(10, –15)
substitute
step 2
Find the distance between the origin and the point B'
the formula to calculate the distance between two points is equal to
we have
O (0,0) and B'(2,-3)
substitute
step 3
Find the scale factor of the dilation
The scale factor is equal to divide the length of segment OB' by the length of segment OB
so
so
