Answer:
y = 5x - 5
Explanation:
Add 5x to the right.
y - 5x + 5x = 5x + 10
y = 5x + 10
Since you want a parallel line, the slope is the same for the new line
y = 5x + b
Now use the given point for the line (3,10)
10 = 3*5 + b
10 = 15 + b Subtract 15 from both sides.
10 - 15 = 15 - 15 + b
b = -5
New line y = 5x - 5
Red Line: y = 5x + 10
Blue Line: y = 5x - 5
