Question 1.

Line parallel to y=7x-8, and passes through (5,-2)

Slope intercept equation:

y= mx+b

Where:

m= slope

b= y intercept

Parallel lines have equal slopes.

So, m= 7

So far:

y= 7x+b

Replace (x,y) by the point given (5,-2) and solve for b:

-2 = 7 (5) +b

-2 = 35 +b

-2-35= b

b = -37

Final equation:

y= 7x-37
