SC Geo - Polygons on the Coordinate Plane & Linear Equations

Front

What is a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments connected end to end.

Front

Define 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 is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on the coordinate plane, written in the form (x, y).

Front

What does it mean for a point to be a solution of an equation?

Back

A point is a solution of an equation if substituting its coordinates into the equation makes the equation true.

Front

How do you find the distance between two points (x1, y1) and (x2, y2)?

Back

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise over run).

Front

What is the equation of a line in slope-intercept form?

Back

Front

What is the y-intercept of a line?

Front

How do you determine if a point lies on a line represented by an equation?

Back

Substitute the x and y coordinates of the point into the equation. If the equation holds true, the point lies on the line.
