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

Mar 1, 2016

$x = 7$,
$y = 7$.

Explanation:

We have to remember that equations are easier to solve if put in the form $y = m x + c$. 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 .
