2x + y < 2 , shade region on grid represented by inequality?
y = - 2x + 2 is that first step
then let x = 0 so y = 2 when x = 0 hence when x = 1 , y = 0 ,
if so do i shade the area bounded by y = 0 , x = 0 ? thanks

What you did is certainly right.
Now , take the first equation.
Next , substitute 0 in place of x and y and check whether the equation is turning to be true or not.
Here , 2 x 0 + 0 < 2
I.e 0 < 2
Which is true.
So if the equation is true , then shade the portion below the line ( the line should be drawn connecting the points which is true for the equation.) , the area pointing towards the origin.All the values below the line facing towards the origin will suite the values of x and y. If it was false , then shade above the line.
