PRACTICE PROBLEMS
1. a) x = (t + 2)/4
t = 4x – 2
Substitute t = 4x – 2 into y = √(6 – 2t)
y = √(6 – 2[4x – 2])
y = √(6 – 8x + 4])
y = √(10 – 8x)
b)
(1,7)
(-4,1)
x starts at one and travels to the left for five units, hence the negative sign.
x = 1 + (-5) t
x = 1 - 5t, t ∈ [0,1]
y starts at seven and travels to the down for six units, hence the negative sign.
y = 7 + (-6) t
y = 7 - 6t, t ∈ [0,1]
When t = 0, x = 1 – 5(0)
When t = 0, y = 7 – 6(0)
x=1–0
y=7–0
x=1
y=7
When t = 1, x = 1 – 5(1)
When t = 0,...
