Question

The point of intersection of the straight lines 9x-y-2=0 and 2x+y-9=0 is

Answer 1

Given: Two equations 9x-y-2=0 and 2x+y-9=0

To find: The point of intersection of the straight lines ?

Solution:

• Now we have given the equations:

                  9x-y-2=0 and 2x+y-9=0

• Solving them, we get:

                  9x - y - 2 = 0  

                  2x + y - 9 = 0

                  11x - 11 = 0

                  x = 1

• Now putting x = 1 in first equation, we get:

                  9(1) - y - 2 = 0  

                  9 - 2 = y

                  y = 7

• So the point of intersection is (1,7).

Answer:

           So the point of intersection is (1,7).
