Answer: 2
Step-by-step explanation: 6 + (-4) = 6 - 4 = 2
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.

Given that the expression for Julia's salary after t years is given by:
25000(1.04)^t
This can be interpreted as follows:
Initial salary is $25000
growth rate is 0.04=4%
thus the correct answer is:
<span>D salary is 25,000 growth rate is 4% per yr</span>
Step-by-step explanation:
Approach: If four numbers a, b, c and d are in proportion then a:b = c:d. The solution is to sort the four numbers and pair up the first 2 together and the last 2 together and check their ratios this is because, in order for them to be in proportion, the product of means has to be equal to the product of extremes.
Answer:
$72
Step-by-step explanation:
Interest= PNR
p = principal
n = number of years
r = rate of interest
i = 6% x 800 x 18/12
i = 72
