Answer: 2
In an equation in the form of y=mx+b, where m is the slope and b is figure 0, b represents the value of y when x is 0 (where the line crosses the y intercept). To tell the y intercept from an equation, you look for the value that is place of b, in this case, 2. To get it from a graph, look for the point at which the line crosses the y intercept. To get it from a table, look for the point where x is 0.
