8x plus 4y equals 5 is 8x + 4y = 5.

8x+4y=20 4y=-8x+20 y=-2x+5 f(x)=-2x+5

-8x + 4y = 28 Add 8x to each side: 4y = 8x + 28 Divide both sides by 4: y = 2x + 7

x=4, y=9 (4,9)

4y - 8x + 12 = 0 4y = 8x - 12 y = 2x - 3 So the slope = 2 y-intercept = -3

8x plus 4y equals 5 is 8x + 4y = 5.

8x+4y=20 4y=-8x+20 y=-2x+5 f(x)=-2x+5

-8x + 4y = 28 Add 8x to each side: 4y = 8x + 28 Divide both sides by 4: y = 2x + 7

4y-8x = 12 4y = 8x+12 y = 2x+3 So the slope is 2 and the y intercept is 3

x=4, y=9 (4,9)

4y - 8x + 12 = 0 4y = 8x - 12 y = 2x - 3 So the slope = 2 y-intercept = -3

If 8x + 4y = 16, then y = - 2x + 4 Thus the slope is -2 and the intercept is 4.

4y-8x+12 = 0 4y = 8x-12 y = 2x-3 The slope is 2 and the y intercept is -3

This can't be solved. You have two varibles.
