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
6x+14y+8x-18y = 14x-4y
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
6x+14y+8x-18y = 14x-4y
Put in this form to see. Y = mX + c 3X - 4Y = - 3 - 4Y = - 3X - 3 Y = (3/4)X + 3/4 --------------------- 8X + 6Y = 14 6Y = - 8X + 14 Y = (- 4/3)X + 7/3 ----------------------- Closer to perpendicular than anywhere near parallel!
4y - 8x + 12 = 0 4y = 8x - 12 y = 2x - 3 So the slope = 2 y-intercept = -3
They add to x+4y simplified
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.
x=4, y=9 (4,9)
It can be simplified to: 12x-3w+13y
