Answer:
1/2
Explanation:
The first thing you want to do is get y by itself. Subtract 7 from both sides:
2x-4y=-7
and then subtract 2x ( the goal is to make your equation look like this: y=mx+b):
-4y= -2x-7
Now, y is mostly isolated, all you have to do now is divide both sides by -4 in order for y to be completely by itself:
y=-2/-4x -7/-4
Simplify completely:
y=1/2x+7/4
Now you have your equation you can easily read it as y=mx+b.
** m is slope & b is the y-intercept**
So your slope would be: 1/2
