Animate a Truck Moving Away from a Vanishing Point in One-Point Perspective
Problem Statement:
The board blocks draw red lines converging to a vanishing point that intersect the corners of the quadrilaterals that make up the truck. The pre-placed blocks generate a loop that counts with x, as well as shapes for the trucks with x-positions as expressions of x. Find the equations for the red lines on the grid, then use these equations and the given equations lines passing through the wheels and windshield to find y-positions for the shapes in terms of x. Then delete the board blocks.
