Across
- 4. A equation that contains a point (x1,y1) and has a slope of m, is found in the format of y-y1= m(x-x1).
- 5. An up-turned or down-turned U-shaped graph
- 7. Add or subtract terms that have the same variable and exponent. Ex: 3x^3+ 6(2x^3-5x)= 13
- 9. An expression that contains at least one variable.
- 12. lines that never intersect. Ex: on the graph, (3,4) & (0,-3) then (3,1) &(-3,-3) do not meet.
- 14. When there is no answer to a system of equations or inequalities. Ex: -13 = 24 this equation has no equation.
- 16. to find solutions to an equation that had a term with a variable to the second power.
- 18. A method used to solve systems by solving an equation for one variable and replacing the resulting expression into the other equation.
- 19. find a solution to an equation or inequality.
Down
- 1. A linear relationship between two variables where there is a non-zero number. Ex: y=kx.
- 2. A collection of terms that has one term that contains a variable to the second power.
- 3. A polynomial consisting of three terms. Ex: 10x^2+ 3a+ 7
- 6. A polynomial consisting of two terms.
- 7. The process of rewriting a quadric equation so that one side is a perfect square trinomial.
- 8. Occurs when a quality/ decreases by the same rate r in each time period.
- 10. A line with slope m and y-intercept b has an equation y=mx+b.
- 11. The line that divides a graph of a number written in exponential form. Ex: x=-4
- 13. Used to solve systems in which one variable is eliminated by adding or subtracting two equations in the system.
- 15. the set of numbers that include all rational and irrational numbers.
- 17. A value that makes the equation true.
