Given:
Big figure = 20 ft
Small figure = 7 ft

Take note: In finding the scale factor, we must make sure that the measurements of both figures are the same sides or line.

20 feet / 7 feet = 2.86 scale factor.

This means that the big figure is 2.86 times bigger than the small figure.

If the arrow had been pointed from the small figure to the big figure.
7 feet / 20 feet = 0.35 scale factor.

This means that the small figure is only 0.35 of the big figure.

Both are scale factors but in different perspectives.

A line contains the points (1, –6) and (–2, 6). What is the slope of a line that is perpendicular to this line?

OlgaM077 [116]

First, find the slope of the line contains the points (1,-6) and (-2,6) using slope formula
m = $\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}$

plug in the numbers
m = $\dfrac{6-(-6)}{-2-1}$
m = $\dfrac{6+6}{-3}$
m = $\dfrac{12}{-3}$
m = -4

Second, determine the slope of perpendicular line
The slope of the perpendicular line is the opposite and reciprocal from the other line. Thus, the slope is $\dfrac{1}{4}$
