Answer

y= 300 miles

Work Step by Step

We are given that the equation is $y=50x$, where y is the distance traveled in a train moving at a constant speed of 50 miles per hour. We can plug in $x=6$ into the equation to calculate the perimeter. $y=50\times6=300$ miles This y-coordinate corresponds to x=6 on the graph of the equation.
