WebNov 4, 2012 · I'm trying to come up with an equation for determining the intersection points for a straight line through a circle. I've started by substituting the "y" value in the circle equation with the straight line equation, seeing as at the intersection points, the y values of both equations must be identical.

WebExplanation: . The general equation of a circle is (x – h) 2 + (y – k) 2 = r 2, where (h, k) represents the location of the circle's center, and r represents the length of its radius. Circle A first has the equation of (x – 4) 2 + (y + 3) 2 = 29. This means that its center must be located at (4, –3), and its radius is √29. WebThis results in a quadratic equation in 𝑥, 𝐴 𝑥 + 𝐵 𝑥 + 𝑐 = 0 . Calculate the discriminant of this quadratic, Δ = 𝐵 − 4 𝐴 𝐶 . If Δ > 0, then the line intersects the circle in two points. If Δ = 0, then the line is tangent to the circle. If Δ < 0, then the line and …
