I believe it would be 2 (answer C).

 

If you redistribute the -2 to the right side of the equation it becomes y=x/-2 - 4/-2 which becomes y=-0.5x+2

So the slope would be -0.5 and it would cross the y-axis at 2.

-2y = x - 4

-2y/-2 = (x - 4)/-2

y = -x/2 + 2

y intercept is computed by plugging in 0 to x:

y = 0/2 + 2

y = 2

y intercept is 2
