Refer Explanation.

Explanation:

y+x=3

y=-x+3

Comparing above equation with y=mx+c ,we get,

m=-1 & c=3

Where, m=slope and c=y-intercept.

graph{3-x [-10, 10, -5, 5]}

We can also draw the graph by plotting random points satisfying equation of line.

"see explanation"

Explanation:

"one way is to find the intercepts, that is where the"
"graph crosses the x and y axes"

• " let x = 0, in the equation for y-intercept"

• " let y = 0, in the equation for x-intercept"

x=0rArry+0=3rArry=3larrcolor(red)"y-intercept"

y=0rArr0+x=3rArrx=3larrcolor(red)"x-intercept"

"Plot the points "(0,3)" and "(3,0)

"and draw a straight line through them for graph"
graph{(y+x-3)((x-0)^2+(y-3)^2-0.04)((x-3)^2+(y-0)^2-0.04)=0 [-10, 10, -5, 5]}
