The equation y=3.5x represents the rate, in miles per hour, at which Laura walks. The graph at right represents the rate at which Peter walks. Determine who walks faster. Explain.
To determine who walks faster, we need to compare the rates at which Laura and Peter walk.
The equation y=3.5x represents the rate at which Laura walks. This means that for every 1 unit increase in x (which represents time in hours), the rate y increases by 3.5 units.
To compare, we need to determine the equation for the graph that represents Peter's rate. Unfortunately, the graph for Peter's rate is not shown, so we are unable to determine it from the given information.
Therefore, with the given information, we cannot determine who walks faster between Laura and Peter.
