Exploring Positive Coordinate Planes

What is the primary purpose of a coordinate plane?

• To draw shapes

• To calculate areas

• To measure distances

• To locate points

Which axis is referred to as the horizontal number line?

• x-axis

• z-axis

• y-axis

• None of the above

Which axis is vertical on a coordinate grid?

• z-axis

• None of the above

• y-axis

• x-axis

What does an ordered pair consist of?

• Two numbers multiplied together

• A set of parentheses with two numbers separated by a comma

• Two numbers in any order

• Two numbers added together

What is the correct sequence of coordinates in an ordered pair?

• Numerical order

• Alphabetical order

• x-coordinate followed by y-coordinate

• y-coordinate followed by x-coordinate

How do you start plotting a point given an ordered pair?

• No specific order is necessary

• Move diagonally

• Move horizontally first

• Move vertically first

How do you determine the x-coordinate of a point?

• Measure the distance from the y-axis

• Measure the distance from the x-axis

• Count units left or right

• Count units up or down

What is the ordered pair notation for a point located at five units right and four units up from the origin?

• (5, 4)

• (-5, 4)

• (4, 5)

• (5, -4)

If a point is on the x-axis, what is the y-coordinate?

• Undefined

• 0

• It varies

• 1

What does the origin of a coordinate plane represent?

• The point (1,1)

• The point (0,0)

• The intersection of axes

• The center of the grid
