Question

How do you find the x and y intercepts for `x+y=7`?

Answer 1

`x = 7`,
`y = 7`.

Explanation:

We have to remember that equations are easier to solve if put in the form `y = mx +c`. So,
`x+y = 7`,
`y = -x + 7`.
Now we simply substitute the value of `x` for `0` to find the `y` intercept, and `y` by `0` to find the `x` intercept. So,
`y = -0 + 7`,
`y = 7`. This is the `y` intercept.
`0 = -x + 7`,
`x = 7`. This is the `x` intercept.

Hope it Helps! :D .
