The y coordinate of (-2, 4) is what?

A cable car is to be built up the side of a hill. The coordinates of the bottom end of the cable are A(1,3,2), while the coordinates of the top end of the cable are B(5,3, 26). A tower is to be placed at P, 1/4 of the way from the bottom of the cable. Find the coordinates of the point on the cable where the tower will be placed.

A line passing through the points (a, 2a) and (-2, 3) is perpendicular to the line 4x + 3y + 5 = 0. Find the value of a.

A billiards table is 8 feet by 4 feet, and has pockets in all four corners and in the middle of the two longer sides; we can visualize this as a rectangle in R2 and assume that the bottom left pocket is at the origin and the top right pocket is at (8, 4). A ball starts at the point (1, 2) and is hit in the direction ⟨5, −2⟩. Does the ball go into a pocket before it bounces off three walls and, if so, which one?

Determine whether the points (-6, 5), (1, 7), and (16, 10) are collinear.
