1. Caught in another nightmare, Tory is moving along the line y = 3x + 2. At midnight, Tory's position is (1,5), the x-coordinate increasing by 4 units every hour. Write parametric equations that describe Tory's position t hours after midnight. What was Tory's position at 10:15 pm when the nightmare started? Find Tory's speed, in units per hour.

correct answer:

a + bi

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
