HW 23.1 Locate Points on a Coordinate Plane Practice to review…I can graph ordered pairs in the first quadrant of the coordinate plane!

An ordered pair names an exact spot on a coordinate plane.

Use the grid below to find the point located at 5 , 4

The first number in an ordered pair tells how many spaces to move ACROSS the grid from left to right.

Think of counting on a horizontal number line.

The second number in an ordered pair tells how many spaces to move UP the grid from bottom to top.

Think of counting on a vertical number line.

Find the point

located at (5, 4).

To find the point (5, 4)

first move 5 → spaces

then move 4 ↑ spaces

Point _____ is at (5, 4).

Now find the coordinates

for Point 𝑋𝑋.

To get to point 𝑋𝑋,

move _____ → spaces

then move _____ ↑ spaces

Point 𝑋𝑋 is at ( _____ , _____ )

Practice to remember… Use the graph on the right for Problems 𝟏𝟏− 𝟏𝟏𝟏𝟏. Write the letter of the point for each ordered pair.
