Answer:
The slope of the green line is 3.
Step-by-step explanation:
<em><u>Definition: </u></em>If the two lines are said to be perpendicular, than the multiplication of their slope is -1.
In other words, the slope of the perpendicular line is the negative reciprocal of the given slope of the line.
Here we are slope of the red line, which is -1/3
Let's take it as "m1"
Let's take "m2" the slope of the green line.
By the above definition,
Given:
Now plug m1 value in the above statement, we get
Multiply both sides by reciprocal of -1/3. The reciprocal of -1/3 = -3
Therefore, the slope of the green line is 3.

Answer:
x = 4
Step-by-step explanation:
The absolute value of 5x is still 5x.
5x - 2 = 18
Add 2 to both sides
5x = 20
Divide both sides by 5
x = 4
