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

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
