With question, marking brainliest + ! *"graph each pair of parametric equations."

1. This is a very easy question as you can just plug in 2 x-values and get the y-value, run a line through it, and you are done. 

For example,
x = 2t
x = 2(2) = 4
x = 2(3) = 6

Now, you know there are points at (2, 4) and (3, 6).

2. This one is a little tricky, but all it's saying is that it has a specified domain. The parametric equation only works for values -2 ≤ t ≤ 3. So, you can do the exact same thing, except your line will only exist for points through the x-values -2 and 3. Let's plug in numbers:

y = t + 5
y = -2 + 5 = 3
y = 1 + 5 = 6

Now you know that this line runs through (-2, 3) and (1, 6). Remember, your line starts at -2 and ends at 3. It can't go any further than that.
