# How do you find the slope and intercept to graph x+y=7?

Write the equation in the form of $y = m x + c$ ,where, $m$ is the slope and $c$ is the intercept of $Y$ axis.
So,given equation is, $x + y = 7$
arranging it we get, $y = - x + 7$
So,slope is $- 1$ and intercept is $7$ graph{x+y=7 [-22.8, 22.81, -11.4, 11.4]}
click on the graph,where it touches $Y$ axis to see the intercept value.
