# parametric equations year 2 watch

1. x=qt+2 and y=t^3 + q

y intercept f curve is (0, 617/25)

I have tried doing the question but im not getting the right answer , could someone start me off . Thanks

Well, what is the question?
3. What exactly is the question?

Well, what is the question?
oh sorry find x and y intercept and find what q is
What exactly is the question?
find x and y intercept coordinates
6. You know that at the y intercept the x value is 0, so you can use that to find t in terms of q and then use other equation to find q.

Well the y-intercept is right there so you don't need to do anything.

To get the x intercept, you want to set then find the value of . Firstly, of course, you'd like to determine what the value of is. To do that, you need to use the fact that the curve crosses which means that at some point , we have and . This yields a system of two equations in two unknowns - solve it to obtain .
