X2 -20x + y^2 - 10y+25=0
identify center of the circle and radius

Center of the circle = (10, 5)

Radius = 10

Step-by-step explanation:

Look at the picture

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
