20 blocks per pound
Step-by-step explanation:
We can see the line of best fit goes through the points (0, 0) and (5, 100). WE will use these to find the slope:

Using our points,

This makes the slope 20 blocks per pound.
Five over there to the power of negative two is
Three squared over five squared
Which is 9 over 25
If she can drive 4180 miles in <em>two </em>weeks, it would make sense that she would drive an average of <em>half </em>that distance in <em>one </em>week. Half of 4180 is 2090, so she averaged 2090 miles each week.
