Question

Darw the graph of liner equation in two variable: x+y=3

Answer 1

The equation is x + y = 3, that means y =3 -x

we want two points on the line to draw the graph of the line.

For this we take x = 0 then workout for y , we get y =3

The second one is obtained by putting y =0 and working for x, we get x= 3

plot these two points (3 0) and (0 3) and join the points and draw the line
