slope is rise/run or (the change in y)/(change in x)
so suppose you have a line with the point (4,-6) on it, and it has a slope of 5/7
so the change in y is 5 for a change in x of 7
so add 5 to the y , and 7 to the x to get (11, -1)
check: what is the slope between (4,-6) and (11,-1) ??
slope = (-1 + 6)/11-4) = 5/7
You can use the above method for every case.
