in the first graph in the first section the slope is positive Rise(5-0=5)/Run(5-0=5) =+1 in the third section why is the sloop is negative Rise(5-0=5)/Run(12.5-10=2.5)=+2 but you say it is a negative number??
@@unconcernedbeast9190 i didn't know how to calculate a slope, the slope should be negative, there is a good video on how to correctly calculate the slope by a channel called mathematics
