Parametric Problem

Question

i have a question on parametric.. The question states

A vector equation $(x,y) = (2,-1) + t(3,2)$. Write as a parametric equation. Show a table with x,y values. Sketch a picture of vector equations. Show at least 4 points.

I don't understand how to do this, this is a test review question, so i have to know this to get prepared for test day after tomorrow. Please help, thankyou

What would you suggest @DeNiSkA ? Im in precalculus so precalc? — amanuel2, May 26 '16 at 00:54

Well, you can plug values in for $t$ in order to get $(x,y)$. For example, using $t=1$ you get $$ (x,y) = (2,-1)+1(3,2) = (5,1) $$ Or, you can write the expressions for $x$ and $y$ independently as $$ x = 2+3t $$ $$ y=-1+2t $$

Hmm tables?.... Graph? – amanuel2 May 26 '16 at 00:55
You can easily create a table for values of $x$ and $y$ given $t$. Have you learned how to graph a point given $(x,y)$ coordinates? – Carser May 26 '16 at 00:56
Oh yeah sorry. My Fault. Thanks a lot Jed. (I was just bieng a douche...) – amanuel2 May 26 '16 at 01:04
Is the persons anwser right here? Im skeptical... http://math.stackexchange.com/questions/1798868/parametric-equations-problem – amanuel2 May 26 '16 at 01:15
@Dsafds Jacob Austin's answer to that question is entirely correct. – N. F. Taussig May 26 '16 at 10:59
@N.F.Taussig thankyou very much kind sir! – amanuel2 May 26 '16 at 20:51
