Point (4,-5)
Required
Determine the line equation
From the question, we understand that the line is parallel to 
This implies that they have the same slope, m
A linear equation is:

Where

By comparison:
and 

Next, we determine the line equation using:

Where
and 


Hence,
<em>Option C is correct</em>
<em />
Step 1. Add 72 to both sides
5y = 7 + 5x + 72
Step 2. Simplify 7 + 5x + 72 to 5x + 79
5y = 5x + 79
Step 3. Divide both sides by 5
y = 5x + 79/5
