Best ResponseYou've already chosen the best response.0A parallel line has the same slope but different y intercept than the 1st equation. So, y = 4x + 9  1st equation rearranged 9 = 4(2) + z  2ns equation where z = y intercept solve for z z = 17 Therefore, the new equation is y = 4x + 17 or 17 = 4x + y

Best ResponseYou've already chosen the best response.0Ok, well \[y=94x\] so the slope is 4 for that line. So the parallel line must also have the slope 4. Now we have for the second line: \[y=4x+b\] So all we need to do now is solve for b. Luckily we have a point given to us so \[9=4(2)+b\] so b = 17
