Answer: The y-intercept (b) is 10.
Explanation:
Use the slope and the point to help you. Plot the point (-3,4) on graphing paper or use geometry software. I use geometry software, it's easier.
You'll need to understand that the slope 2 can also be written as 2/1 (rise/run). Go up 2 units and go to the right 1 unit, then plot a point. Keep going until one of the points lies on the y-axis. The y-coordinate of that point is the y-intercept. So, the y-intercept (aka "b") is 10.
You're welcome, and I have a nice day! :D
