y = 8x-47 or y-1 = 8(x-6)

Work Step by Step

The original equation (8x - y = 9) can be rewritten as: y = 8x - 9 From this, we see that the slope of the original line is 8, so any line parallel to this line must also have the same slope of 8. Since we now have the point (6, 1) and the slope (8), we can use point-slope form to get: y-1 = 8(x-6). This can also be rewritten as: y = 8x-47
