Definitions
bivariate data- a set of points where the two sides of a two-variable linear inequality are equal.
function- an input- output relationship that has exactly one output for each input.
input- the value substituted into an expression or funtion
linear equation- an equation whose solutions form a straight line on a coordinate plane.
linear function- a function whose graph is a straight line
nonlinear relationship- a relationship between two variables in which the data do not increase or decrease together at the same rate.
ordered paira pair of numbers that can be used to locate a point on a coordinate plane.
output- the value that results from the substitution of a given input into an expression of function.
proportional relationship- a relationship between two quantities in which the ratio of one quantity to the other quantity is constant.
rate of change- a ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable.
slope- a measure of the steepness of a line on a graph; the rise divided by the run.
slope-intercept form- a linear equation written in the form y=mx+b, where m represents slope and b represents the y-intercept.
x-coordinate- the number first in an ordered pair; it tells the distance to move right or left from the origin (0,0).
y-coordinate- the second number in an ordered pair; it tells the distance to move up or down from the origin (0,0).
y-intercept- the y-coordinate of the point where the graph of a line crosses the y-axis.
