Which of the following describes the graph of an equation with two variables? The graph contains two points that are connected b
y a line and are the solutions to the equation. The graph does not represent every solution for the two variables due to the scale of the axes. The graph represents all of the solutions for the equation regardless of the shape. The graph represents the solution in which one of the variables is true.

The triangles formed by a rod and its shadow and a tree and its shadow are similar triangles, so the ratios of their heights to the lengths of their shadows are equal.
Let x be the height of the tree. Setting the ratios equal, we get:
