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 <==
