Coordinate Planes and Perimeter

Your house is at the coordinate (5, 4) and the playground is at (-3, 4). If each number on the number line represents a block, how many blocks is it from your house to the playground?

• 6 blocks

• 5 blocks

• 9 blocks

• 8 blocks

Using absolute value, how would you find the perimeter of this irregular shape?

• You would count the spaces around the edge.

• Find the absolute values and subtract then multiply the line segments.

• First, find the ordered pairs then absolute value of each line segment, by subtracting because they are all in the same quadrant. Last, add all line segments.

How many quadrants are on the coordinate plane?

• 1

• 2

• 3

• 4

There is a point on the coordinate plane at (-1, 7). If you reflect this point ver the X-axis, what would your new ordered pair be?

• (1,7)

• (-1,-7)

• (1,-7)

• (-1,7)
