Step-by-step explanation:
1. x - 3t, y = -2t, t - 4
t - 4 = 0 (this is because it is a linear equation and it has no number after the equal sign so it is 0)
t = 4
x - 3t = 0
subt t for 4
x - 3(4) = 0
x - 12 = 0
x = 0 + 12
x = 12
y = -2t
subt t for 4
y = -2(4)
y = -8
:. The parametric equation for #1 matches with ordered pair letter C
3. x = t, y = t², t = 5
t = 5
subt t for 5
x = t
x = 5
y = t²
subt t for 5
y = 5²
y = 25
:. The parametric equation for #3 matches with ordered pair letter A
4. x = t² + 3, y = t² -2, t = 2
t = 2
subt t for 2
x = t² + 3
x = 2² + 3
x = 7
y = t² - 2
subt t for 2
y = t² - 2
y = 2² - 2
y = 2
:. The parametric equation for #4 matches with ordered pair letter B
This is the best I can do for now
still trying to find the calculation for no 2 but it is D
hope the rest helps.
