The correct answer is:

15 blocks.

Explanation:

"As the crow flies" means in a straight line. This will be a diagonal line connecting the two locations.

Elizabeth's house can be represented by the ordered pair (1, 4), where the x-coordinate represents the street number and the y-coordinate represents the avenue number. Using this same system, the restaurant is represented by the ordered pair (10, 16). To find the length of the line segment that would connect the we use the distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}
\\=\sqrt{(10-1)^2+(16-4)^2}
\\=\sqrt{(9)^2+(12)^2}
\\=\sqrt{81+144}=\sqrt{225}=15$
