Problem 219

Show that the slope of the segment joining \((1,2)\) and \((2,6)\) is equal to the slope of the segment joining \((5,15)\) and \((10,35)\)

Expert verified

The slopes of the segments joining \((1,2)\) and \((2,6)\) and \((5,15)\) and \((10,35)\) are equal, as we calculated both slopes to be 4 using the slope formula \( slope = \frac{y_2-y_1}{x_2-x_1} \).
