The horizontal interval joining $A$A $\left(-4,5\right)$(4,5) and $B$B $\left(-7,5\right)$(7,5) has been graphed on the number plane. Find the length of the interval.

The points $P$P $\left(-3,-2\right)$(3,2), $Q$Q $\left(-3,-4\right)$(3,4) and $R$R $\left(1,-4\right)$(1,4) are the vertices of a right-angled triangle, as shown on the number plane.

Consider the interval $AB$AB on the graph.
