The answer is the product of their slope is -1.
First, let's break this down. Perpendicular lines are line with opposite reciprocal slopes. Opposite meaning the inverse sign and reciprocal meaning flipped.
For instance,
If a line had the slope of 5, its inverse would have a slope of -1/5.
Now, if we multiply these numbers together,
5 * -1/5 = -1
The 5's cancel out.
This works for any two perpendicular lines
Answer:
696
Step-by-step explanation:
6x+19.98=200
200-19.98=6x
X= 200-19.98/6
= solve for it.
You can add numbers mentally if there are zero's behind them.
