Question

A flashlight shines straight up into the sky, 9 ft to the right of a tent located at the origin. For which values of A, B, and C will Ax+By=C represent the beam of light?

please say the answer as a= b= c=

Answer 1

The right answer is "a = 1, b = 0, c = 9"

Explanation:

As the direction would have to be vertical, this same direction should therefore seem to have a consistent or constant x-coordinate.

∴ The equation a line is:

⇒
`x=9`

On comparing it with:

⇒
`Ax+By=C`

We get,

`A=1\\`

`B=0`

`C=9`
