Question

Rewrite the parametric equations by eliminating the parameter. Select ONE.

X = 2t + 3 and Y = t - 2

Answer Choices:

Y = 3x + 1
Y = x - 7 / 2
Y = x + 5
Y = x - 5 / 2

Answer 1

`Y=(X-7)/2`

Explanation:

we have

`X=2t+3` -----> equation A

`Y=t-2` ----->
`t=Y+2` -----> equation B

Substitute equation B in equation A

`X=2(Y+2)+3`

`X=2Y+4+3`

`X=2Y+7`

solve for Y

`2Y=X-7`

`Y=(X-7)/2`
