Plot the intercepts to graph the equation. 2x - 3y = 6 Use the graphing tool to graph the equation. Use the intercepts when drawing the line. If only one intercept exists, use it and another point to draw the line.

X²+y²-10x-6y = 23
(x²-10x)+(y²-6y)=23
We need to complete square for x and y groups.
(x²-2*5x+5²) + (y²- 2*3y+3²)=23 +5² +3²
(x-5)²+(y-3)² = 57  - sometimes this form is called standard
(x-5)²+(y-3)² = (√57)² 
(5,3) is vertex of the circle, and √57 is the radius of the circle.
Sometimes this form called is standard:
