Best ResponseYou've already chosen the best response.0Slope is defined by conventoin as rate of change of y wrt x

Best ResponseYou've already chosen the best response.1positive slope implies y increases as x increases negative slope implies y decreases as x increases

Best ResponseYou've already chosen the best response.0you can say it like that, but it's possible that x increases and slope is zero

Best ResponseYou've already chosen the best response.1yes  that is different case: zero slope means y remains the same as x increases

Best ResponseYou've already chosen the best response.1dw:1328378129883:dw if you look at this line, the slope is negative. it could be calculated by either working out the changes from A to B OR by working out the changes from B to A. so, from A to B we get:\[slope=\frac{15}{51}=\frac{4}{4}=1\] and from B to A we get:\[slope=\frac{51}{15}=\frac{4}{4}=1\]

Best ResponseYou've already chosen the best response.1so you can see that a negative slope can be worked out with either a negative change in x or a negative change in y. it depends on how you pick your two points.
