For the second one all you need is a grid you can just print one out on google

2. anonymous

It's a little complicated not having a grid.

Midpoint formula is $(\frac{ x_1 + x_2 }{ 2 },\frac{ y_1 + y_2 }{ 2 })$

11. zpupster

$x_1 = 9,\ x_2=-3,\ y_1 = -9, \y_2 = 7$

go to desmos .com for a grid

The center of a circle on a coordinate plane is located at the point (2, –1). One endpoint of the diameter is located at (0, –2). What are the coordinates of the other endpoint of the diameter of the circle?

$d=\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$
