Write the equation in the form of $y=mx+c$ ,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.
