Fill in each blank so that the resulting statement is true T
     Fill in each blank so that the resulting statement is true.  The pair of equations x = squareroot t and y = 2t - 1 are called  equations and the common variable t is called the. The graph of this pair of equations is called a(n).  The pair of equations x = squareroot t and y = 2t - 1 are called  equations and the common variable t is called the  The graph of this pair of equations is called a   
  
  Solution
These are parametric equations and , \'t\' is the parameter
Now lets find the x-y equation from the parametric equations:
x = sqrtt ; y= 2t -1
square the first equation : x^2 =t
substitute t in y = 2t-1
y = 2x^2 -1
The equation we got is of parabola
The graph of the pair of equations is parametric curve
