Slope of means that for every positive difference of 4 in the horizontal direction, there is a positive difference of 3 in the vertical direction. So pick any point you like in . Then move 4 units to the right, stop and move 3 units up, stop and mark your second point. Two points is sufficient to uniquely determine a line in .

The slopes of perpendicular lines are negative reciprocals of each other.
