Emily took 39 minutes to bike the biking section of a race. It then took her 9 minutes per mile to run the running section of the race. She represented this with the equation t = 39+9m, where t represents the total time she was racing in minutes and m represents the number of miles she ran in the running section.

    Slope=9, y-intercept = 39

    Step-by-step explanation:

    The equation is already in y=mx+b form, where m is the slope and b is the y-intercept

    (rearrange positions of 9m and 39 to get t=9m + 39)

    So, the slope is 9 and the y-intercept is 39
