For what value of y does the graph of 4x - 1/2y = - 12 cross the y-axis?

Answer:6

Step-by-step explanation: First step is to transfer your equation into slope-intercept form (mx+b+y). You can do this using inverse operations.

4x-1/2y=-12

+1/2y + 1/2y

4x=-12+1/2y

+12 + 12

4x+12=1/2y

1/2 1/2 1/2

2x+6=y

Now that your equation is in slope intercept form just look at theb value for your answer

mx+b+y

2x+6=y

Your b value always represents where your line (on your graph) touches the y axis
