Will mark ! use the drop downs to answer the following questions about the distance between the points (−5, 1) and (2, −1). what is the distance of the horizontal leg? what is the distance of the vertical leg? use the pythagorean theorem. what is the distance between the two points?

The distance between the horizontal legs be the distance between the 'x' values '-5' and '2'. 2+5=7 (It is +5 because the distance between -5 and 0 is 5*) 
The distance between the horizontals is 7

Same with the vertical points, as the distance is 2. (1+1=2)

Considering that the pythagorean theorem is the a^2+b^2=c^2, and 'a' and 'b' are the sides, then you plug in '7' and '2', making the equation 7^2+2^2=c^2
49+4=c^2
53=c^2
c=sqrt(53)
Hope this helps.
