Rewrite the given parametric equations in Cartesian form

Question

Rewrite the given parametric equations in Cartesian form:

x(t)2t-1

y(t)=t+4

 

A. y=(1/2)x+(7/2)

B. y=(1/2)x+(9/2)

C. y=2x-1

D. x+4

Answer 1

x(t) = 2t-1
y(t) = t+4  so t = y - 4; therefore x =2(t-4) -1

and all you have to do is simplify this Cartesian equation.
