What is the equation of the line parallel to y=3x+6 that contains the point (3,9)?

Answer 1

y=3x

Explanation:

Lines that are parallel have the same slope. So we are looking for an equation with the same slope of 3x.

Since we have this information, we can plug in the numbers & solve

y=mx+b

9=3(3)+b

9=9+b

0=b

so the equation would be y=3x
