4?
A. -4
B. -2
C. 2
D. 4
What is the y-intercept of the graph of -2y = x –
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
