Start with the given distance formula
d=sqrt%28%28x%5B1%5D-x%5B2%5D%29%5E2%2B%28y%5B1%5D-y%5B2%5D%29%5E2%29 where is the first point and is the second point

d=sqrt%28%28-3-4%29%5E2%2B%280-0%29%5E2%29 Plug in x%5B1%5D=-3, x%5B2%5D=4, y%5B1%5D=0, y%5B2%5D=0

d=sqrt%28%28-7%29%5E2%2B%280%29%5E2%29 Evaluate -3-4 to get -7. Evaluate 0-0 to get 0.

d=sqrt%2849%2B0%29 Square each value

d=sqrt%2849%29 Add

d=7 Simplify the square root

So the distance between (-3,0) and (4,0) is 7 units
