Parametric Equations

Question

Rewrite the parametric equations by eliminating the parameter. 

 

x = 4t + 1 

and 

y = t - 3

Answer 1

Follow those instructions!

 

t = y+3

 

Now substitute into other equation, giving you an equation involving x & y.  IT'S A ST. LINE!

Answer 2

x = 4t + 1

 

 

y = t - 3

 

t =y+3

 

substitute the value of t in first equation

 

x=4t+1

x = 4(y+3)+1

x=4y +12 +1

x = 4y+13
