No.

x - 8x = 1 Perform the indicated subtraction on the left side: -7x = 1 Divide each side of the equation by -7 : x = - 1/7

Since the highest power of 'x' in the equation is '1', there's one solution.

x=1, y=1

8x - 8y = 1Add 8y to each side:8x = 8y + 1Subtract 1 from each side:8x - 1 = 8yDivide each side by 8:y = x - (1/8)

8x - 19 = 3x + 1 5x -19 = 1 5x = 20 x = 4

-8x = 32Divide each side by 8:-x = 4Multiply each side by -1:x = -4

It is a linear equation in a single unknown variable, x.

(4 ± i2) where i2 = -1

(1, 1)

It would be perpendicular to a line with the equation Y = 1/8 X.

There is only one equation that is given in the question and that equation is not a direct variation.
