A tunnel is constructed with a semielliptical arch. The width of the tunnel is 80 feet, and the maximum height at the center of
the tunnel is 30 feet. What is the height of the tunnel 4 feet from the edge? Round your answer to the hundredths place. 4.01 feet
9.37 feet
13.08 feet
29.85 feet
These would have infinite solutions because this is a slope-intercept equation. Since you are provided with the y-intercept in both, you can put anything in for the slope and it will work.
