Question

the point (p, q) lies on the line joining the
points (-4, 5) and (-5, 7), then show that
2p+q+3=0.​

Answer 1

Answer:

p=-9/2 , q =6

Step-by-step explanation:

x1=-4 ,y1=5 ,x2=-5 ,y2=7

p=-4+(-5)/2

=-4-5/2

=-9/2

q=5+7/2

=12/2

=6

2p+q+3=0

2*-9/2+6+3=0

-9+9=0

0=0

Hence it is proved.
