SOLUTION
GIVEN:
Two straight lines have equations y=px+4 and py=qx−7, where p and q are constants.
The two lines meet at the point (3,1)
TO DETERMINE
The value of q
EVALUATION
Here the given equation of the lines are
Now the two lines meet at the point (3,1)
Since equation (1) passes through the point (3,1)
Again Equation (2) passes through the point (3,1)
FINAL ANSWER
Hence the required value of q = 2
