Pre-image point N(6, -3) was dilated to point N'(2, -1). What was the scale factor used?
blagie [28]

Question 1

Let the scale factor be k.

Then, we have the mapping

N(6,-3)\to N'(6k,-3k)

This implies that:

(6k,-3k)=(2,-1)

We equate any corresponding component find the value of the scale factor k.

6k=2

k=\frac{2}{6}

k=\frac{1}{3}

Hence the scale factor is  \frac{1}{3}

Question 2:

The midpoint of any two points can be calculated using the formula;

(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})

We want to find the midpoint of (-8, 5) and (2, -2).

(\frac{-8+2}{2}, \frac{5+-2}{2})

(\frac{-6}{2}, \frac{3}{2})

The midpoint is:

(-3, \frac{3}{2})
