Endpoint: (1, 2), midpoint: (-2,-4)
please help

Use the slope formula and slope-intercept form y=mx+b to find the equation.

y=2x

Use the distance formula to determine the distance between two points.

Exact Form:

3√5

Step-by-step explanation:

Explanation: The fastest way to find the missing endpoint is to determine the distance from the known endpoint to the midpoint and then performing the same transformation on the midpoint. In this case, the x-coordinate moves from 4 to 2, or down by 2, so the new x-coordinate must be 2-2 = 0.
