Question

Eliminate the parameter.

x = 3t, y = t + 7

Answer 1

y = (x/3) + 7

y = 3x + 7

y = 3x - 7

y = (x/3) - 7

Answer 2

Answer 3

Same process as before. Find a simple substitution based on how the parameter is used in \(x\) and \(y\). Since both \(x\) and \(y\) have \(t\), you can say
\[x=3t~\Rightarrow~t=\frac{x}{3}\]
Now plug that into \(y\).

Answer 4

y = x/3 + 7

Answer 5

Yes
