Using slope intercept form, we can solve for the slope first:
22 - 2/11-1
20/10, or 2 in reduced form, is our slope.
Now that we have the slope, we can refer to any of the ordered pairs to identify b:
y = mx + b
Let’s plug in our answer:
22 = 2(11) + b
22 = 22 + b
Because 22 = 22, our initial value is 0. Hence, b = 0.
Our equation is y = 2x or y = 2x + 0; either of these equations verifies the answer.
