Answer:
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
Answer: The slope is -3/2
