See the given explanation

Explanation:

By taking subsequent variables as zero, one by one we can plot the entire line the equation plots easily
For this particular equation, #y=-x+2#

So, first, let's take #y=0\implies0=-x+2\impliesx=2#
So the first point for plotting is #(2,0)#

Next let's take #x=0\impliesy=0+2\impliesy=2#
So the second point for plotting is #(0,2)#

So the points to be considered are #(2,0)" and "(0,2)#
Drawing a graph, we see how the equation plots itself.
graph{y+x=2 [-10, 10, -5, 5]}

Note, we could have solved this by intercept form too, but generally the above method is more better as it helps save time.
