Chapter 3 - Introduction to Graphing - 3.5 Slope - 3.5 Exercise Set: 67


slope = $\frac{29}{98}$

Work Step by Step

Convert each measurement to inches by using the fact that 1 ft = 12 inches. 8 ft 2 inches = $8(12)+2=98$ inches 2 ft 5 inches = $2(12)+5=29$ inches Solve for the slope by dividing the rise (or height) by the run (horizontal distance). slope = $\dfrac{29\text{ inches}}{98 \text{ inches}}=\dfrac{29}{98}\approx 0.2959$
