Help on a function type question

Juliet and Mercutio are moving at constant speeds in the *xy*-plane. They start moving at the same time. Juliet starts at the point (0, −6)

and heads in a straight line toward the point (10, 5), reaching it in 10 seconds. Mercutio starts at (9, −18) and moves in a straight line. Mercutio passes through the same point on the *x*-axis as Juliet, but 2 seconds after she does.

How long does it take Mercutio to reach the *y*-axis? (Round your answer to three decimal places.)

How would I do this problem? Thank you!

Re: Help on a function type question

You'll want to start by finding the equations of both lines. You are given two points for Juliet explicitly, and it is implied that wherever Juliet has her x-intercept is also on Mercutio's line. You can use this point as the second point for Mercutio. After doing so, you'll want to calculate the distance and rate of speed of Juliet. Use this to find out how long it takes her to reach the x-axis. Add 2 to this number to find Mercutio's rate of speed. After that, determine how long it takes for him to reach the y-axis.

The numbers part is up to you.
