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
P = 2, q = 4
p = 3, q = 1
p = 5, q = 3
p = 6, q = 2
Explanation
\(\frac{p + q}{2}\) = 4
p + q = 8 ....(i)
\(\frac{p - 2}{2}\) = q
p - 2q 2 ....(ii)
q = 2, p = 6
3q = 6
p + q = 8 ....(i)
\(\frac{p - 2}{2}\) = q
p - 2q 2 ....(ii)
q = 2, p = 6
3q = 6
