Coordinate Planes

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

What are the x-axis and y-axis?

Back

The x-axis is the horizontal line on a coordinate plane, while the y-axis is the vertical line.

Front

What does a point's coordinates (x, y) represent?

Back

The coordinates (x, y) represent the position of a point on the coordinate plane, where 'x' is the distance from the y-axis and 'y' is the distance from the x-axis.

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, start at the origin (0,0), move 'x' units along the x-axis, and then 'y' units up or down along the y-axis.

Front

What is the origin in a coordinate plane?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect.

Front

What is the distance from a point to the x-axis?

Back

The distance from a point to the x-axis is the absolute value of its y-coordinate.

Front

What is the distance from a point to the y-axis?

Back

The distance from a point to the y-axis is the absolute value of its x-coordinate.

Front

What does it mean for a point to be inside a triangle on a coordinate plane?

Back

A point is inside a triangle if it lies within the boundaries formed by the triangle's vertices.

Front

How can you determine if a point is inside a triangle?

Back

You can determine if a point is inside a triangle by checking if the point satisfies the inequalities formed by the triangle's sides.

Front

What is a vertex in a triangle?

Back

A vertex is a corner point of a triangle where two sides meet.
