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:
The original regular price for the coat is $90
Step-by-step explanation:
The given information in the question are;
The percentage that was off (removed) from the sale price = 30%
The sale price at which Jerry bought the coat = $63
Whereby the regular price = P, we have;
P - 30% of P = $63
P - 0.3×P = $63
P×(1 - 0.3) = $63
0.7·P = $63
P = $63/0.7 = $90
Therefore, the regular (original) price for the coat = $90
The coat regular price at which the coat is displayed is at $90.
