What is the slope of all lines perpendicular to the line y=(2/3)x+7

The slope is -3/2

Step-by-step explanation:

A line that is perpendicular to another has the slope that has the sign reversed and is the reciprocal.

Example:  Find the line perpendicular to y = 3x

First, you flip the sign which makes 3 into -3

Next, you make the reciprocal which makes -3 into -1/3

Problem:  Find the line perpendicular to y = (2/3)x + 7

First, you flip the sign which makes 2/3 into -2/3

Next, you make the reciprocal which makes -2/3 into -3/2

 The slope is -3/2

v: l•w•h÷2.

v: 20•6•8 ÷2

v: 960÷2

v: 480
