First, find the slope of the line between these points.

#### Explanation:

The formula for slope m =

m =

m =

m =

m =

The slope of a line perpendicular to this one has a slope that is the negative reciprocal of m.

So, the new slope is

**Practice exercises:**

- Here is the graph of a linear function. Find the slope of the line perpendicular to this one.

graph{y = 1/2x + 1 [-10, 10, -5, 5]}eh equations of the lines perpendicular

- Below are linear function equations or linear function characteristics. Find the equations of the lines perpendicular to these functions:

a) 2x + 5y = -3

b) y - 2 =

c) Has an x intercept at (2,0) and a y intercept at (-5,0).

Good luck!
