The line \(x = -1\) is a vertical line which passes through -1 ... The shape has been reflected in the line \(y = 1\). The equation of a straight line graph has the form \(y = mx + c\), where ...

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.
