Answer: last option.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
Find the slope of the line with this formula:

Choose two points from the table and substitute the coordinates into the formula. Then, the slope is:

By definition, the line intersects the y-axis when the value of "x" is zero. So, based on the table, the y-intercept is:

Then the equation of the line is:

The line intersects the x-axis when the value of "y" is zero, then substituting
into the equation of this line, and solving for "x", you get:

So, the point of intersection with the x-axis is:

Since the table shows the distance from school as a function of time, you can conclude that meaning of the x-intercept in this scenario is: "The distance away from the school".
