Hope this helped!
Answer:

Step-by-step explanation:
step 1
Find the slope of the given line
we have

isolate the variable y

The slope of the given line is

step 2
Find the equation of the line that goes through the point (1,5) and is parallel to the given line
Remember that
If two lines are parallel then their slopes are equal
therefore
we have


substitute in the equation of a line in slope intercept form


solve for b

substitute
