Question

How do you use the cover-up method to solve for the x and y intercept?

Answer 1

I suppose that "cover-up" is a friendlier term for "setting a variable equal to zero," so if you are looking for the `x`-intercept of a line, then set `y` equal to zero, and for `y`-intercept, set `x`-equal to zero.

Example

Let us find the `x,y`-intercepts of the line

`2x+3y=12`.

To find the `x`-intercept, set `y=0`.

`=> 2x+3(0)=12 => 2x=12 => x=6`

So, the `x`-intercept is `6`.

To find the `y`-intercept, set `x=0`.

`=> 2(0)+3y=12 => 3y=12 => y=4`

So, the `y`-intercept is `4`.
