Sec 3/4 E Math T04-Q27 - Applying coordinate gradient to a ramp

A straight access ramp rises \(75\) cm over a horizontal distance of \(700\) cm. On a scale drawing, the lower end is represented by \(A(0,0)\) and the upper end by \(B(700,75)\).

1. Find the gradient of \(AB\).
2. The design limit is a gradient not exceeding \(0.125\). State, with a reason, whether the ramp satisfies the limit.
