#d = 5# units

Distance =#sqrt((x_2-x_1)^2 + (y_2-y_1)^2# Here, #x_2# is 10, #x_1# is 7, #y_2# is 8, #y_1# is 4.

Substituting and solving we get: #d = sqrt((10-7)^2 + (8-4)^2# #d = sqrt(3^2 + 4^2)# #d = sqrt(9+ 16)# #d = sqrt(25)# #d = 5# units

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
