Answer: line R
Step-by-step explanation: because it crossing through the starting and ending points
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.
I'm pretty sure it's 3,000,000, "Basically, if the power is positive, you move the decimal point in the integer that many places to the right ex:
3.14 x 10 ^ 3 would be 3140.
If the power is negative, you move the decimal point to the left ex:
3.14 x 10 ^ -3 would be 0.000314" according to Yahoo
