Answer: The campers will be from their car after 12 hours.
Step-by-step explanation:
<h3> The missing graph is attached.</h3>The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" the y-intercept.
We can pick two points on the line graphed and substitute the coordinates into this formula to find the slope:
Choosing the points (0,4) and (2,10), we get:
We can susbstitute the point (0,4) and the slope into and solve for "b":
Then, the equation of this line is:
Since the distance in miles is represented on the y-axis and the time in hours is represented on the x-axis. we can rewrite the equation as:
Finally, in order to calculate the distance in miles that the campers will be from their car after 12 hours, we need to subsitute into the equation and evaluate. Then we get:
