Jonathan set up an obstacle race in the park and made a graph of the results of his data. Find the intercepts and slope. Include units in your answers
x-intercept = 8 seconds
y-intercept = 20 yards
slope = -1 yards per second
x-intercept = 20 yards
y-intercept = 8 seconds
slope = -2.5 yards per second
x-intercept = 8 seconds
y-intercept = 20 yards
slope = -2.5 yards per second
x-intercept = 20 yards
y-intercept = 8 seconds
slope = -1 yards per second
What is the equation for the graph?
