Remembering positive or negative gradients
Line A is negative.
Line B is positive.
To remember this:
Going from left to right
Push positively (+)
Down Dash quickly (-)
A graph is read from left to right.
As the mountaineer travels from left to right he goes up the side of the mountain and increases in height (+ve) as this side of the mountain has a positive gradient (+ve).
A second mountaineer is also travelling from left to right having already reached the top she is descending in height (-ve) as this side of the mountain has a negative gradient (-ve).
