Question

08.04a Parametric Equations:
Graph each pair of parametric equations.
x = 2t
y = t + 5; -2 ≤ t ≤ 3

Please help! I am not sure how to solve this at all, I have tried everything! Medal will be awarded to who helps me!

Answer 3

well, there are a few ways to approach this, one is to solve t for x, and sub in the y part; this creates a more usual y = f(x) format

Answer 4

the other is to table it
x y
t: 2t : t+5
-2: -4 : 3
-1: -2 : 4
0: 0 : 5
1: 2 : 6
2: 4 : 7
3: 6 : 8

Answer 5

x = 2t ; t = x/2

2(-2) <= x <= 2(3)
-4 <= x <= 6

y = t + 5 ; y = x/2 + 5 is a simple enough line to graph

Thank you so much!!
