Question

graph this parametric equation
x = 2t
y = t + 5, -2 ≤ t ≤ 3

Answer 1

every time i try graphing it my calculator says you cannot graph an ineqaulity?

Answer 2

You don't need a graphing calculator.
Eliminate the parameter. It should be smooth sailing from there.

Answer 3

how do you do that :o

Answer 4

x = 2t --> t = x/2

Plug in x/2 for t in the second part of the parametric equation.

Answer 5

OH

Answer 6

THANKS MAN

Answer 7

Oh no, I forgot to talk about the parameters.
The given interval is -2 ≤ t ≤ 3
But, since we're using 'x' as the independent variable, we need to find the interval of x.

x = 2t -> When t = -2, x = -4
When t = 3, x = 6
So, the interval you should be graphing on is: -4 ≤ x ≤ 6
