Apply the distance formula:
.
d = sqrt[(x1 - x2)^2 + (y1 - y2)^2]
.
Plug in the values for x1, x2, y1 and y2.
Perform the operations underneath the radical sign.
Find the square root of the result.
d - sqrt[(-1-3)^2 + (2-(-4)^2]
.
.
Apply the midpoint formula. The midpoint is the same as finding the average of each point. Add the values together and divide by two:
(x1 + x2)/2 represents the x value of the midpoint.
.
(y1 + y2)/2 represents the y value of the midpoint.
.
Plug in the values and perform the necessary operations. The final answer should be in the format of (x, y).
