Me out i can't fail this the coordinates of point a on a grid are (−2, −4). point a is reflected across the y-axis to obtain point b. the coordinates of point b are −4). numerical answers expected!

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, 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.
