Best ResponseYou've already chosen the best response.0ok so the parallel line must have the same slope, which in this case would be 3. We can see that because if we rearrange the equation, we get y = 73x. Then we know that the new line must have the form y=3x+b. To find b, all you got to see if there is a point given to you, which you know for sure will be contained in the line. So plug in y = 1 and x=9. Can you do the rest?
