- 1. The equation of a straight line in the form y = mx + b. M is the slope of the line and b is its y-intercept.
- 4. A sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number. The fixed non-zero number is called the common ratio.
- 6. A pair of angles that are formed by intersecting lines. They are opposite from each other and are congruent.
- 7. The side of a triangle that is opposite of the right angle in a right triangle. You can find this side using the pythagorean theorem.
- 11. The equation of a straight line in the form y − y1 = m(x − x1). M is the slope of the line and (x1, y1) are the coordinates of a given point on the line.
- 12. Has endless non-repeating digits to the right of the decimal point. Often expressed with a radical.
- 14. A linear equation in two variables is of the form Ax + By + C = 0. A and B are the coefficients, C is a constant term, and x and y are the two variables.
- 16. A form of writing a mathematical concept like an equation, number, or an expression in a form that follows rules. Expresses in the form ax+by=c.
- 17. A number without fractions. Must be positive with no decimal.
- 18. A way of expressing numbers that are too large or too small to be conveniently written in decimal form. Where a number is multiplied by 10 to the power of something.
- 19. Any number or expression raised to the power of zero. Will always equal 1.
- 20. Positive numbers we use when counting. Can also be zero.

- 2. A formula used to find the hypotenuse of a right triangle. Expressed using the equation a2 + b2 = c2
- 3. The formula used to find the distance between two points. The formula is √[(x₂ - x₁)² + (y₂ - y₁)²].
- 5. A sequence where each term increases by adding/subtracting some constant. The constant is called the common difference.
- 8. The formula used to find the middle of two points. You can find this point by using the formula (x1 + x2)/2, (y1 + y2)/2.
- 9. A number that describes both the direction and the steepness of the line. Found using the equation m=(y2-y1)/(x2-x1).
- 10. Represents a portion of a whole. Also referred to as a ratio.
- 13. Straight lines that are always the same distance apart from each other. The lines will never touch each other even as they go on forever.
- 15. The distance a number is from 0 in the number line. Will always be a positive number.
