A two-dimensional coordinate system is defined by a pair of intersecting horizontal and vertical number lines referred to as axes.
On the horizontal axis, to the right of 0, the values are positive.
On the horizontal axis, to the left of 0, the values are negative.
On the vertical axis, above 0, the values are positive.
On the vertical axis, below 0, the values are negative.
What are the coordinates of point Q?
Each line represents a half unit.
Point Q is located by moving 2 and a half units to the right and 3 and a half units up.
The coordinates of point Q are (2.5, 3.5) or (, ) or (, ).
Which point is located at (3, -2)?
From the origin, move 3 units to the right and 2 units down.
Point S is located at (3, -2).
Point (k, m) is plotted on the grid. What are the coordinates of point (k, -m)?
The plotted point, (k, m), is (1, 2), which means k is 1, and m is 2.
The question asks for (k, -m).
k does not change.
-m means the opposite of m, which is -2.
So, (k, -m) is (1, -2).
