Across
- 7. the value of y when x = 0. the beginning, where the line touches the y-axis, or "b"
- 10. of change, slope. rise over run, change in y over the change in x
- 11. slope, no slope the slope of a line that is graphed horizontally
- 12. the horizontal change of a line, change in the x-value, x2 minus x1
- 13. opposite of positive, left side of zero , or below zero on a number line
- 15. rate, means a rate for one of something, 5 bags of chips cost $5, how much for one bag of chips
- 16. the measure of steepness. Mathematically, slope is calculated as "rise over run"
- 17. the coordinate that rises or falls (to go up or down) from the origin, output, range
- 19. equal rate, same in value, having a constant ratio to another quantity 1/2 = 4/8 etc
- 20. opposite of negative. above zero or to the right of zero. gain.
Down
- 1. intercept form, one of the forms used to calculate the equation of a straight line, given the slope of the line and intercept it forms with the y-axis (y=mx + b),
- 2. slope of a line that is a vertical line.."line that goes Up N Down"
- 3. line, creates a straight line
- 4. the coordinate that runs left to right from the origin, first value of an ordered pair, the input, domain
- 5. incline, or grade of a line is measured by the absolute value of the slope. "how slanted is it?"
- 6. change, run..change in the x-values...x1 minus x2
- 8. triangle, a triangle with one 90-degree angle
- 9. a relation between a set of inputs having one output each."x does not repeat"
- 14. the vertical change of a line, change in the y-value, y2 minus y1
- 18. change, occurs when the graph of a figure is moved up or down on the coordinate plane. the rise
- 21. (0,0) . the bullseye of the coordinate grid
