The line parallel to y=9x+4 that passes through (2,7)

y = 9x + 4....the slope here is 9. A parallel line will have the same slope

y = mx + b
slope(m) = 9
(2,7)...x = 2 and y = 7
now we sub into the formula and find b, the y int
7 = 9(2) + b
7 = 18 + b
7 - 18 = b
-11 = b

so ur parallel equation is : y = 9x - 11 <==
