If the equation of a perpendicular bisector of a triangle is y = 2x + 7, what is the slope of the side that it is bisecting? Exp

lina2011 [118]

Answer:

slope = - $\frac{1}{2}$

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 7 is in this form with slope m = 2

This line is perpendicular to the side it bisects.

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{2}$

I NEED HELP PLEASE, THANKS

First, find the scale factor.

8.4 / 7 = 1.2

9 / 7.5 = 1.2

7.2 / 6 = 1.2

Since both solids are different sizes, the solids aren't congruent.

The size ratio for all the sides are:

8.4:7

9:7.5

7.2:6

Since the scale factor isn't 1:1 this also proves that the solids are NOT congruent.

Since both solids are the same kind of shape and have an identical scale factor, the solids are similar.

Best of Luck!
