Find the slope between the two points: (9,9) and (12,15)
15-9= 612-9= 36/3= 2
Slope = Change in y / Change in xBetween (9, 9) and (12, 15).We would use the coordinates from the second point minus that from the first point.1st point = (9, 9), 2nd point = (12, 15)Slope = (15 - 9) / (12 - 9) = 6 / 3 = 2 Slope = 2
