Writing Linear Functions

Writing Linear Functions 1.3 - Solution

We have been asked to explain and correct Ron-Jon's mistake when finding the slope. Let's see how he might have calculated in order to obtain 0.4.0.4. 0.4=25=runrise 0.4=\dfrac{2}{5}=\dfrac{\text{run}}{\text{rise}} This is incorrect as rise and run have been reversed. The slope should have been calculated by dividing the rise by the run. m=riserun=52=2.5 m=\dfrac{\text{rise}}{\text{run}} = \dfrac{5}{2}=2.5
