+1855 A line and a circle intersect at A and B, as shown below. Find the distance between A and B.
The line is x = 4, and the equation of the circle is x^2 + y^2 = 25.
+37165 Find the two y values corresponding to x = 4
4^2 + y^2 = 25
y = + - 3 so now find the distance between (4,3) and ( 4, -3)
distance = 6 between A and B
