75 points to the first person to answer all of these with all work shown. geometry. you

(x – h)2 + (y – k)2 = r2

h is your x value and the opposite of k is your y value. r is the radius

so, in the first equation, your center would be (-4,2) and the radius would be 5 because you take the square root of r

So plot (-4,2) and count 5 units left, right, up, and down from that point.

Do the same thing for the second circle. The center is (2,-1) and the radius is 5.6 units

The other graphs are pretty much the same way. 

For number 7, plot the center and the other set of coordinates. Count the distance between the center and that point and that is your radius

For number 6, plot the center, and to get the radius, take half of the diameter.

For the last one you have to use the distance formula
