find the slope using the distance and put the points into the point-slope equation
y1 - y= m times (x-x1)
so if you have the points (3,4) and the slope is 5 then the equation would look like this:
4-y= 5 (x-3)
then distrubute the 5
so its 4-y = 5x -15
then solve it for y
y1 - y= m times (x-x1)
so if you have the points (3,4) and the slope is 5 then the equation would look like this:
4-y= 5 (x-3)
then distrubute the 5
so its 4-y = 5x -15
then solve it for y
