Answer:
ca 32.89
Explanation:
Firstly we need to know how far it is between the two points in both directions
In the x direction the distance is 8 - (-3) = 11
In the y-direction the distance is -42 -(-11) = -31
Then to find the shortest distance between the two points find the hypotenuse of the triangle we just made
31^2 + 11^2 = h^2
961 + 121 = h^2
1082 = h^2
h = ca 32.89
