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
