Given y+x=-2

y=-2-x Subtract x from both sides.

y=-x-2 Rearrange the terms

Looking at y=-x-2

We can see that the equation is in slope-intercept form y=mx+b

Where the slope is m=-1 and the y-intercept is b=-2

Since b=-2

This tells us that the y-intercept is.

Remember the y-intercept is the point where the graph intersects with the y-axis

So we have one point (0,-2)
