Question

How do you write an equation of the line whose x-intercept is 2 and y intercept is -4?

Answer 1

`2x-y-4=0.`

Explanation:

We can use the following well-known Result :

If `a and b` are the `X and Y"-intercepts"` of a line, its eqn. is

`x/a+y/b=1`

In our Example, as `a=2, b=-4," so the eqn. follows :"`

`x/2+y/-4=1, i.e., 2x-y-4=0.`
