Answer:
1) 8
2) -2
3) 6
Step-by-step explanation:
1) First, find the pattern in the table, with X the pattern is +1, but with Y the pattern is +2. So to find the Y-intercept in the table you need to subtract 1 from X and subtract 2 from Y. The answer is 8.
2) On a graph it is really easy, it is where the line touches the Y-axis, in this case, it is -2. The answer is -2.
3) With the equation y=mx+b, the M is the rise/run and the B is the Y-intercept, and the B in the equation is 6. The answer is 6.
