The answer is a.) -27
subtract 11 from 38
27 keeps the negative sign because -38 is larger than 11
The slope of the line perpendicular to the line seen in the picture is - 2 / 3.
<h3>How to determine the slope of a line perpendicular to another line</h3>
The slope of a function is determined by the secant line formula and is defined by the following expression:
m = Δy / Δx (1)
Where:
- Δx - Change in the independent variable.
- Δy - Change in the dependent variable.
- m - Slope of the line.
Besides, by analytical geometry, the slope of a line perpendicular to another line is equal to:
m' = - 1 / m
If we know that Δx = 2 and Δy = 3, then the slope of the line perpendicular to the line seen in the picture is:
m = 3 / 2
m' = - 1 / (3 / 2)
m' = - 2 / 3
The slope of the line perpendicular to the line seen in the picture is - 2 / 3.

The simple interest on the principal amount of $725 at a rate of 3.25% for 6 months is $736.78
<h3>What is simple interest? </h3>
Simple interest is calculated on the loan principal amount or the initial deposit into a savings account. It can be determined by using the formula:
where:
- P = principal = $725
- R = rate = 3.25%
- T = time = 6 months = 0.5 years
S.I = $736.78
