Question

If the system of linear equations 3x+2y-4=0, ax-y-3=0 represent intersecting
      lines, then the value a is________​

Answer 1

Answer:

Any number except -1.5

Step-by-step explanation:

In intersecting lines,

A1/A2 ≠ b1/b2

So if we make a1/a2=b1/b2, we can find the exception number.

A1=3,b1=2,b2=-1

3/a=-2

A=3/-2

A=-1.5

Therefore, for any value of a except -1.5, these two lines will intersect.

Hope this helps.
