I'll do the first two to show you how to solve these problems

Remember, the four quadrants are in these regions of the coordinate system:

#1

First plot the point (3,4)

Start at the origin (where the the x and y axis intersect)

Now move your pencil 3 units to the right
We move 3 units in this direction since the x-coordinate is 3 (its the first number of the pair)

Now go 4 units up
We move 4 units in this direction since the y-coordinate is 4 (its the second number of the pair)

Plot a point where the pencil lands

So here is the point (3,4)

Now looking at the drawing of the quadrants, you can see that the point (3,4) is in the first quadrant

#2
Now let's plot the point (5,-2)

Start at the origin (where the the x and y axis intersect)

Now move your pencil 5 units to the right
We move 5 units in this direction since the x-coordinate is 5 (its the first number of the pair)

Now go 2 units down
We move 2 units in this direction since the y-coordinate is -2 (its the second number of the pair)

Plot a point where the pencil lands

So here is the point (5,-2)

Now looking at the drawing of the quadrants, you can see that the point (5,-2) is in the fourth quadrant
