Question

Which quadrant does (1, 1) lie?

Answer 1

Quadrant 1

Explanation:

The best way to remember what quadrant a set belongs to is to know the positive and negative axes. This is applicable to all sets of integers.

Let (x,y) be our guide. We all know that in a set, the first number is the value of x (horizontal axis) while the second number is the value of y (vertical axis).

For the horizontal axis: to the right: POSITIVE; to the left: NEGATIVE

For the vertical axis: upward: POSITIVE; downward: NEGATIVE

Now, here are the signs for each quadrant. ALWAYS.

Quadrant I : both x and y are positive (+x, +y)
Quadrant II : x is negative, y is positive (-x, +y)
Quadrant III : both x and y are negative (-x, -y)
Quadrant IV : x is positive, y is negative (+x, -y)
