Answer
y = -88x + 99
Explanation
Step 1: Find the slope by doing the rise over run equation, which is y2-y1 / x2-x1. Plug in x and y numbers based on the table. So, the slope (m) = -88.
Step 2: Figure out the real equation: y=mx+b. Plug in numbers that you have to find the missing number, the y-intercept (b).
y=mx+b --> 11 = -88 * 1 + b --> 99 = b
Step 3: Plug everything into the y=mx+b equation.
