Question

Cassidy wrote the linear equation y=5x+4. Then, she wrote the equation of the line that is parallel to y=5x+4 and that passes through (8,–2). If her new equation is in the form y=5x+b, what is the value of b?

Answer 1

All you need to do is plug in the point.
y=5x+b
(-2) = 5(8) + b
-2 = 40 + b
b = -42
