Question

I did almost all the questions already, the only ones I need are d and h!.

Answer 1

SOLUTION

(d) Two coordinates where we could build a bridge are

$(-3,7.5)\text{ and }(3,7.5)$

(h) The graph showing the roads, potholes and river is shown below

So, from the graph, the pothole is at a coordinate (-4, 33/5) (undefined).

So the bridge is constructed in front of the pot hole, between (-3, 7.5) and (3, 7.5)
