To solve this problem, all you need to do is make a standard graphing equation. The first step is finding mode using two points from the table. We'll use (1, 70) and (2, 90).
From the work, we've found that the slope of this equation is 20.
Next, we need to finish writing the equation and plug in the coordinates to solve for the y-intercept.
Now we have all the information we need to write our equation, which is:
y = 20x+50
Hope this helps!
