When y is zero what does x have to be? This gives you the point (x, 0) use the equation to find x.

if we add y to both sides of the equation we get x = y+2

if we then subtract 2 from both sides we get y = x -2 , (which is in the form of a linear equation y=mx + c, )

if we then choose 3 values of x, say x=0,1,2 and work out the corresponding y values, we have our 3 points.

to graph this we simply draw a straight line that passes through all three points
