Answer:
Dave should stop at Springfield.
Step-by-step explanation:
As shown, Gilmore is 26 miles away.
And Dave is driving to Gilmore but he wants to stop for lunch when he is about halfway there.
That means he wants to stop around miles.
And Springfield is 15 miles away that is nearest to 13 miles.
Hence, Dave should stop at Springfield.

We can model this situation as a system of linear equation, where n is the number of nickels and q is the number of quarters.
Solving the system of equations, there are 67 nickels and 19 quarters.

Answer:
A line passing through the points (-1,-4),(0,0) and (1,4)
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
<u><em>Verify each case</em></u>
Part 1) A line passing through the points (-4,0) and (0,-2)
This line not represent a direct variation, because the line not passes through the origin.
Part 2) A line passing through the points (-5,4) and (0,3)
This line not represent a direct variation, because the line not passes through the origin.
Part 3) A line passing through the points (-4,-6) and (0,3)
This line not represent a direct variation, because the line not passes through the origin.
Part 4) A line passing through the points (-1,-4),(0,0) and (1,4)
The line passes through the origin
Find out the value of k
For the point (-1,-4)
substitute
For the point (1,4)
substitute
The linear equation is
This line represent a direct variation
