Question

Find the x- and y-intercepts of the graph of -x +y = 8. State your answers as

whole numbers or as improper fractions in simplest form.

Answer 1

Given:

The equation is

`-x+y=8`

To find:

The x- and y-intercepts.

Solution:

We have,

`-x+y=8`

Put x=0 in the given equation to find the y-intercept.

`-(0)+y=8`

`y=8`

Put y=0 in the given equation to find the x-intercept.

`-x+(0)=8`

`-x=8`

`x=-8`

Therefore, the x-intercept is -8 and the y-intercept is 8.
