Question

Fine the value of a if ax + by + 3 = 0 meet x - axis at 3

please correct answer​

Answer 1

Answer:

Ok Let me tell you. The equation at which the line intersects x-axis is y=0

Step-by-step explanation:

If it intersects x-axis so we need to put y as 0

After that we will do ax+0+3=0

So ax=-3

We are given that it intersects x-axis at 3 so we will put x as 3

Now a(3)=-3

So a=-1
