Step by step
The question
Question: which quadrant is (1, 4) in?
(1, 4)
1 Read the signs
The first number is x.
1 is positive.
So the point is right of the y-axis.
x = 1 → +
The second number is y.
4 is positive.
So the point is above the x-axis.
y = 4 → +
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
Right and up: (+, +).
That is quadrant Ⅰ.
= (+, +) → quadrant I
4 Check
Let's check: plot it.
From 0, go right 1.
Then go up 4.
Put a dot.
The dot is in quadrant Ⅰ.
So the answer is right!
Let's look back.
First: read the signs.
Then: name the quadrants.
Then: find the quadrant.
Last: check.
Answer
= (+, +) → quadrant I
