coordinate grids

What does the x-coordinate represent?

• The vertical position of a point on the coordinate grid.

• The distance from the origin to the point along the y-axis.

• The horizontal position of a point on the coordinate grid.

• The angle of a point relative to the origin.

If a point is at (2,3), what is its x-coordinate?

• 1

• 2

• 3

• 4

In the ordered pair (7, 8), which number is the x-coordinate?

• 7

• 8

• 6

• 9

What is the formula to find the distance between two points (x1, y1) and (x2, y2)?

• Distance = √((x2 - x1)² + (y2 - y1)²)

• Distance = |x2 - x1| + |y2 - y1|

• Distance = (x2 - x1) + (y2 - y1)

• Distance = √((x2 - x1) + (y2 - y1)²)

Which axis runs up and down?

• x

• y

• z

• w

If a point is at (5,1), what is its y-coordinate?

• 0

• 1

• 2

• 3

Where is R on the coordinate plane?

• (2,3)

• (4,6)

• (1,5)

• (3,7)

What is a coordinate grid?

• A grid formed by two perpendicular lines (axes) that intersect at a point called the origin.

• A system used to measure temperature in degrees.

• A type of graph used to display statistical data.

• A method for organizing information in a table format.

What does the y-coordinate represent?

• The horizontal position of a point on the coordinate grid.

• The vertical position of a point on the coordinate grid.

• The distance from the origin to the point on the grid.

• The angle of the point relative to the x-axis.

What are the four quadrants in a coordinate grid?

• Quadrant I, II, III, and IV

• Quadrant A, B, C, and D

• Quadrant 1, 2, 3, and 4

• Quadrant Alpha, Beta, Gamma, and Delta
