Answer key and explanations
-
D. \((3, 7)\)
An ordered pair \((x, y)\) shows the location of a point. The x-coordinate (3) tells how far right from the origin, and the y-coordinate (7) tells how far up. The point is at \((3, 7)\).
-
D. Where the x-axis and y-axis meet
The origin is the point where the x-axis and y-axis intersect, labeled as \((0, 0)\).
-
C. \((0, 0)\)
The origin is located at \((0, 0)\), where both coordinates are zero.
-
A. P
Point P at \((5, 0)\) has a y-coordinate of 0, so it lies on the x-axis.
-
B. Point A
Point A is located 2 units right (x-coordinate) and 8 units up (y-coordinate), so it is at \((2, 8)\).
-
A. \(6\)
In an ordered pair \((x, y)\), the first number is the x-coordinate. For \((6, 4)\), the x-coordinate is \(6\).
-
B. \(9\)
In an ordered pair \((x, y)\), the second number is the y-coordinate. For \((4, 9)\), the y-coordinate is \(9\).
-
A. \(5\) units
The x-coordinate tells how many units right from the origin. For \((5, 2)\), move \(5\) units right.
