8x - 8y = 1

Add 8y to each side:

8x = 8y + 1

Subtract 1 from each side:

8x - 1 = 8y

Divide each side by 8:

y = x - (1/8)

Q: 8x - 8y equals 1 the solution for y is equals to?

No. That is because 2 - 8x is an algebraic expression, not an equation. And since it is not an equation, it does not have a solution.

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

If: -8y-7 = -8+8y Then: -7+8 = 8y+8y And: 16y = 1 So: y = 1/16

Rewrite the equation in the slope intercept form: y = mx + c Thus: 4x - 8y = 12 8y = 4x - 12 y = 4/8x - 12/8 = 1/2x - 3/2 and then, the gradient is the coefficient of x viz 1/2 or 0.5

The answer to that is a graph, which I cannot show you (it's not possible on this text box). I will tell you the function form of the problem: y= -10/8x + 1/4

(1, 1)

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

The inverse function is obtained by interchanging corresponding values of x and y and then transposing the resulting equation to make y the subject. f(x) = y = 8x + 5 therefore f-1(x) = x = 8y + 5 : 8y = x - 5 : y = (x - 5)/8 The inverse function of y = 8x + 5 is y = (x - 5)/8

I guess you mean the coordinates of the point of contact for x and y. The line is a tangent when the solution to where they meet has a repeated root, ie: y = kx + 1 → x = (y - 1)/k y² = 8x → y² = 8(y - 1)/k → ky² = 8y - 8 → ky² - 8y + 8 = 0 has repeated roots when the discriminant is zero, ie: 8² - 4 × k × 8 = 0 → 8 - 4k = 0 → k = 2 → point of contact is: 2y² - 8y + 8 = 0 → y² - 4y - 4 = 0 → (y - 2)² = 0 → y = 2 → 2 = 2x + 1 → 2x = 1 ← x = ½ → point of contact is (0.5, 2) and k = 2.
