How would you find the slope of the line containing the points P(4, 9) and R(57, 73)?

Slope is defined as the difference in the vertical axis divided by the difference in the horizontal axis, going left to right (s = dy/dx).  P has a lesser x co-ordinate, so it will be R - P in this case, giving us (ry - py) / (rx - px):

i think the amount would be $140.62
