Step by step
The question
Question: which quadrant is (0, 4) in?
1 Read the signs
The first number is x.
It is 0.
So the point is on the y-axis: not left, not right.
The second number is y.
4 is positive.
So the point is above the x-axis.
2 Name the quadrants
Draw the grid.
The two axes cut it into four parts.
Each part is called a quadrant.
3 Find the quadrant
x is 0, so the point is on the y-axis.
A point on an axis is not inside any quadrant.
Careful!
(0, 4) is on the line between quadrant Ⅰ and quadrant Ⅱ.
So it is in neither of them.
4 Check
Let's check: plot it.
From 0, go up 4.
Put a dot.
The dot is on the y-axis, not inside a quadrant.
So the answer is right!
Let's look back.
First: read the signs.
Then: name the quadrants.
Then: find the quadrant.
Last: check.
