TermDefinition
ordered pair a pair of numberrs (x,y) used to located a point in a coordinate plane. the first number is the x-coordinate and the second number is the y-coordniate
coordinate plane a coordinate plane is formed by the intersection of a horizontal number line , usually called the x-axis and a vertical line usually called y-axis
x-axis the horizontal line in a coordinate plane
y-axis the vertical line in a coordinate plane
x-coordinate the first coordinate in an ordered pair ,which indicates how many nits to move to the left or the right from the orgin
y-coordinate the second in an ordered pair, which indicates how many units to move up or down from the origin
linear equation an equation that has two or more variables
solution of a linear equation all of the points on a line
slope a ratio of the change in y(the rise) to the change x (the run) between any two points on a line. it is measure of steepness of a line
rise the change in y in two points on a line
run the change in x between two points on a line
slope-intercept an equation written in the form y=mx+b. the slope of the line is m and y-intercept is b
x-intercept the x-coordinate in an ordered pair, which indicates how many units you move up or down from the origin
y-intercept the y-coordinates of the point where the line crosses the y-axis
standard form a linear equation written in the form ax+by=c where a and b are both not zero
systems of linear equations a set of two or more linear equations in the same variables
solution of a system of linear equations an ordered pair that makes each equation in a system of linear equations true
