Across
- 4. lines that never intersect. Ex: on the graph, (3,4) & (0,-3) then (3,1) &(-3,-3) do not meet.
- 6. Add or subtract terms that have the same variable and exponent. Ex: 3x^3+ 6(2x^3-5x)= 13
- 9. To find a solution to an equation or inequality.

- 5. An expression that contains at least one variable.
- 7. Occurs when a quality/ decreases by the same rate r in each time period.
- 8. When there is no answer to a system of equations or inequalities. Ex: -13 = 24 this equation has no equation.
