The length of the completed tunnel can be calculated using the equation . If the project will be completed 86 days after the TBM was introduced, the length of the completed tunnel will be feet.
The y - intercept of an equation is the value of y when x is substituted with zero. From the given equation, y = 25x + 225 Substituting, y = (25)(0) + 225 y = 225 Thus, the y - intercept of the given equation is 225.
