Draw a vertical line, using a ruler, from the given amount up to the line. Draw a horizontal line, using a ruler, from the line across to the \(y\)-axis. Read the value on the \(y\)-axis.

The standard equation for a parabola is ... The parabola's axis of symmetry (x = h) is a vertical line passing through the vertex, so as demonstrated above, this is x = 1. From the focal point ...
