Question

# A human being can swim at a maximum rate of 7.4 feet per second. The function y = 7.4x describes how many feet y a person can swim in x seconds. Graph the function. Use the graph to estimate the maximum number of feet a person can swim in 4.5 seconds.

1 of 3

Since $y=7.4x$ is a linear function which has a graph of a line, we need at least two points to graph it.

When $x=0$, $y=7.4(0)=0$ so one point is $(0,0)$. When $x=10$, $y=7.4(10)=74$ so another point is $(10,74)$. Plot the two points and connect with a straight line as shown:
