Question

P(0,5),Q(15,-4) are two points . If the point (5,a) lies on the line PQ then the value of a is​

Answer 1

the question is wrong

value is point p or q is incorrect

Answer 2

eq of PQ=y+4/x-15=-4-5/15-0

15(y+4)=-9(x-15)

15y+60+9x-135=0

9x+15y-75=0

substitute point in this eq.

9(5)+15(a)-75=0

45+15a=75

15a=30

a=2
