find the points of intersection of the line x-y+2=0 and the circle 3Xsquare + 3Ysquare -29x -19y +56 =0. also find the length of the chord intersepted.
Dear Student!
Equation of the given line is x – y + 2 = 0 ...(1)
Equation of the circle is 3x2 + 3y2 – 29x – 19y + 56 = 0 ...(2)
Solving (1) and (2), we get
When x = 5, we get
5 – y + 2 = 0 (Using (1))
∴ y = 7
When x = 1, we get
1 – y + 2 = 0 (Using (1))
∴ y = 3
Coordinates of the end points of the chord intercepted by the given line and the given circle are (5, 7) and (1, 3).
∴ Length of the chord
Cheers!
