If M(4, q) is the mid-point of the line joining L(p, -2) and N(q, p). Find the values of p and q

To find the values of p and q, we can use the midpoint formula, which states that the midpoint of a line segment between two points (x1, y1) and (x2, y2) is ((x1+x2)/2, (y1+y2)/2). Here, we are given that M(4,q) is the midpoint of the line joining L(p,-2) and N(q,p). So we know that: - The x-coordinate of M is the average of the x-coordinates of L and N: (p+q)/2 = 4 - The y-coordinate of M is the average of the y-coordinates of L and N: (-2+p)/2 = q Simplifying the first equation, we get: (p+q)/2 = 4 p+q = 8 q = 8-p Substituting this into the second equation, we get: (-2+p)/2 = q (-2+p)/2 = 8-p -2+p = 16-2p 3p = 18 p = 6 Therefore, the values of p and q are: - p = 6 - q = 8-p = 2 So the correct option is p = 6, q = 2.
