Question

If the mid point (x,y) of the line joining (3,4) and (p,7) lies on 2x+2y+1=0, then what will be the value of p?​

Answer 1

Answer:

p= -15

Step-by-step explanation:

midpoint of the two points is given as

x = (3 + p)/2 and y = (7 + 4)/2

2x = 3+p and 2y = 11

since the po8nt lies on the line it satisfies equation of the line

3+p + 11 + 1 = 0

p = -15
