What is the y-intercept of the line represented by the equation below? y = –2x – 1 a.–2 b.–1 c.1 d.2

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.
