2) We have two points on this inequality (-1,0) and (0,1)
Slope [ 1 -0 ] / [ 0 - -1] = 1/1 = 1
If we had a solid line the equation would be
y= x + 1
But we have a dotted line
So
The equation is either
y < x + 1 or y > x + 1
To see which one is correct, pick a point in the shaded area and test it in the equations ..I'll pick (0,2)
2 < 0 + 1
Not true
So the equation is
y > x + 1
Rearrange as
x - y + 1 < 0
