Unit 4-6 Vocabulary Quiz

Master math vocabulary! Quiz on functions, relations, slope, and systems of equations.

1. A(n) relation is a relationship between sets of values.2. A(n) function is a rule that determines one unique y value for a given x value; each x has one y.3. A relation is linear if it has a constant rate of change and it creates a straight line when graphed.4. A relation is nonlinear if the rate of change is different and it doesn’t create a straight line when graphed.5. A(n) ordered pair is a pair of numbers used to locate a point of a graph.6. A(n) mapping is a visual representation of how x-values and y-values are related.7. The input is what you put into a function; the independent variable; the x-value.8. The output is what you get out from a function, based on the input; the dependent variable; the y-value.9. The slope is a measure of the steepness and direction of a line.10. The y-intercept is where the line crosses the y-axis; the initial value; what y is when x=0.11. The rate of changedescribes how the y-values change per 1 change in x.12. Slope-intercept form is y = mx + b, where m represents the slope and b represents the y-intercept13. A(n) system of equations is a collection of two or more equations with a same set of unknowns; we try to find values that will satisfy every equation in the system.14. The intersection point is where two or more lines cross.15. If a system of equations has no solution, there are no values that will make the equations true.16. If a system of equations has infinite solutions, ANY value will make the equations true.
