Question

Use the given information to write the standard form equation of a circle:

a) x²+y²+10x+14y+70=0 translated 1 unit to the right and 2 units down. ​

Answer 1

The formula for the equation of a circle is (x – h) 2 + (y – k) 2 = r 2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. If a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
