- 3. a monomial or a sum or difference of monomials
- 4. of Change A ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable.
- 6. the signed vertical distance between a data point and a line of fit
- 7. method a method used to solve systems of equations in which one variable is eliminated by adding or subtracting two equations of the system
- 9. The x-coordinate(s) of the point(s) where a graph intersects the x-axis.
- 11. Function A function that can be written in the form y=mx+b, where x is the independent variable and m and b are real numbers. Its graph is a line.
