Question

Find the value of p if the slope of the line joining the points (4,6) and (8,p) is 3/2

Answer 1

Answer:

Correct option is

C

19

−69

Let's assume the slope joining the points (3,−9) and (p,2p+3) is m

⇒m=

p−3

2p+3−(−9)

=

p−3

2p+12

From the given data we know that slope m=

7

−5

⇒

p−3

2p+12

=−

7

5

⇒14p+84=−5p+15

⇒p=−
