Across
- 1. The steepness of a line on a graph. It is calculated by the change in y divided by the change in x between two coordinate points (x, y) on the line. When an equation is in slope-intercept form, slope is represented by the variable m.
- 7. Two shapes are congruent if their corresponding sides and angles are all equal.
- 8. A graph that displays bivariate data so that each member of the population is represented by a dot. By looking at the overall pattern of dots on the graph, you can get a general idea about the relationship between the two variables.
- 9. Data relating to a variable that places the population into different groups, such as race or geographic location.
- 10. root When a number, n, is cubed, and it produces another number, x, then n is the cube root of x (n^3 = x). For instance, (cube root of 27) = 3
Down
- 2. This theorem addresses the connection between a right triangle's hypotenuse, c, and its other two sides, a and b. The theorem is a^2 + b^2 = c^2.
- 3. A number that can be written as a fraction. Rational numbers include integers and fractions, as well as many decimals and radicals.
- 4. The angle ∠ABC consists of the two rays from B that pass through A and C respectively. The spread between the directions of these rays is measured in degrees (°), and this measure is occasionally written m∠ABC, or sometimes ∠ABC, or even ∠B. 360° is a complete revolution.
- 5. A set of data that contains information about two variables, such as annual income and education level for individuals.
- 6. Numbers that cannot be written as fractions. Examples of irrational numbers include pi, radical two and Euler's number.
- 8. A shape is similar to another shape if its sides and angles are all proportional to the corresponding sides and angles of the other shape.
