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:

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