Answer:


y=-x+7

The graph in the attached figure

Explanation:

we have


x+y=7

This is the equation of the line in standard form

Convert to slope intercept form


y=mx+b

where

m is the slope

b is the y-intercept

Isolate the variable y

subtract x both sides


x+y-x=-x+7

simplify


y=-x+7

The y-intercept is the point (0,7)

Find the x-intercept

For y=0


0=-x+7\\x=7

The x-intercept is the point (7,0)

Plot the intercepts and join them to graph the line

see the attached figure
