Answer 1

Once we have the table we can graph the points in the plane.

To graph a point (x,y) in the plane we have to start at the origin, then we will count x units in the horizontal direction (to the left if x is negative and to the right if x is positive); then from the point we reach while moving horizontally we are going to count y units in the vertical direction (up is y is positive and down if y is negative).

Let's take for example the first point (-2,-1). We start at the origin and move two units to the left, and from there one unit down. That way the point will be graph as shown

If we do this with all the point we get

Finally, to get the graph of the equation we join the points with a line
