(x+ 1)？ +(y+2)？ =8

Center radius (-1, -2) r=2√2

The distance from the center of the circle to the straight line d=|-4+6-2|/5=0.

So the straight line 4x-3y=2 passes through the center of the circle.

So there are four points * * * The distance from the circle to the straight line 4x-3y=2 is the root number 2.
