Across
- 3. The y-coordinate of the point where the graph of a line crosses the y-axis. It is the point (0, b). In the table it is the point where x = 0.
- 5. The second number in an ordered pair; it tells the distance to move up or down from the origin (0,0).
- 7. m A measure of the steepness of a line on a graph; the rise divided by the run. Can be referred to as the rate of change. Represented by m. Can be determined using the side of right triangles (slope triangles) on a graph.
- 8. of Change A ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable. (slope)
Down
- 1. An equation whose solutions form a straight line on a coordinate plane and is in the form of y = mx + b.
- 2. Proportional Relationship (situation) A relationship between two quantities in which of the ratio of one quantity to the other quantity is constant.
- 4. The first number in an ordered pair; it tells the distance to move right or left from the origin (0,0).
- 6. non-proportional situation A relationship between two quantities in which of the ratio of one quantity to the other quantity is NOT constant. (has a y-intercept or starting point other than 0)
