Answer:
1) 1/2
Explanation:
first you must put "y" on its own, so the equation would then look like:
a) 4y = 2x - 18 or b) -4y = -2x + 18,
either or works, then you divide both sides of the equation by the coefficient on y, where on a it is 4 and on b it is -4.
Whatever you get, you would end up with the same answer,
y = 1/2x -18/4,
thus the slope would be 1/2
