And then in general form. You've got the ax squared plus B Y squared. Plus CX plus dy plus C equalsMoreAnd then in general form. You've got the ax squared plus B Y squared. Plus CX plus dy plus C equals 0. So let's check out our first. Example.
Equation of a Circle: The standard form of the equation of a circle is ( x − h ) 2 + ( y − k ) 2 = r 2 where is the center of the circle and is the radius. Radius: The radius is the distance from the center of a circle to any point on the edge.
Plus y plus 1 squared equals 11 plus 4 plus 1 is 16. So my radius is 4. And my H and K. My CenterMorePlus y plus 1 squared equals 11 plus 4 plus 1 is 16. So my radius is 4. And my H and K. My Center Point is at 2 minus. 1. So now that I have this information I can graph. We go over to. And down one.
A standard form equation looks like this: Ax + By = C where A, B, and C represent numbers. For example, a standard equation with numbers looks like this: 5x - 3y = 8 (A = 5, B = -3, and C = 8). If you are asked to solve for either the slope or y-intercept, you will need some formulas.
One. Our radius tells us that we're going to go 2 in every direction from the center so we're goingMoreOne. Our radius tells us that we're going to go 2 in every direction from the center so we're going to go out two in each direction. And then we would simply connect. These dots with a circle.
And just pick one of the endpoints. That's a point on our circle. And put it in for X. And Y. AndMoreAnd just pick one of the endpoints. That's a point on our circle. And put it in for X. And Y. And what we'll do is we'll solve for R squared.
h 2 + y k 2 = r 2.
