First, all of these numbers are even, so halving everything would be a nice place to start:2x-y=1
Then, rearrange to get y on one side of the equation:
2x-y=1
-y=1-2x
y=-(1-2x)
y=2x-1
Finally, check the coefficient of x (number being multiplied by x):
y=2x-1
Therefore the slope of this line is 2.

4x+2y = 6 2y = -4x+6 y = -2x+3 Perpendicular slope is 1/2
Slope = 4
Impossible to say because the equal, the positive and/or the negative signs or instructions are missing in your question.
-8x -2y = 16 Algebraically rearrange into the form ' y = mx + c'. Hence 2y = -8x - 16 Divide both sides by '2' y = -4x - 8 Hence 'm' the slope is '-4' 'c' the y-intersect is '-8'. NB The equation can be in numerous forms : - -8x - 2y - 16 = 0 8x + 2y + 16 = 0 -8x = 2x + 16
4x-y+3 = 0 -y = -4x-3 y = 4x+3 Therefore: the slope is 4 and the y intercept is 3
