4x - 2y = 8
Rearrange into the 'straight line ' form of y = mx + c
Hence
-2y = -4x + 8
y = 2x - 4
The 'c' value is the y-intercept, which '-4' . The steepness/gradient of the slope is '2'.

4x-2y = 2
4x2 - 4x + 2xy - 2y = 4x(x - 1) + 2y(x - 1) = (x - 1)(4x + 2y) = 2(x - 1)(2x + y)
4x+2y = 20 2y = -4x+20 y = -2x+10
4x-2y = 3 -2y = -4x+3 y = 2x-1.5 in slope intercept form
you have to solve for the variable for example. 4x + 2y = 8. you would solve for y. so you subtract the 4x and you do the same to both sides and you get 2y = -4x + 8. you then divide everything by 2 to get y by itself and you end up with y = -2x + 4
