- 2. the x-intercept is the x-coordinate of a point where a graph crosses the x-axis.
- 9. positive correlation is when y tends to increase as x increases, the two sets of data have a positive correlation.
- 10. no correlation is when x and y are not related , the two sets of data have.
- 12. the slope-intercept form of a linear equation of a nonvertical line is y=m(slope)x+b(y-intercept).
- 13. extrapolation is predicting a value outside the range of known values.
- 14. a linear equation is an equation that models a linear function.
Down
- 1. negative correlation is when y tends to decrease as x increases, the two sets of data have a negative correlation.
- 3. interpolation is estimating a value between two know values.
- 4. y-intercept of a graph is the y-coordinate of a point where the graph crosses the y-axis
- 5. scatter plot is a graph that relates two different sets of data by displaying them as ordered pairs.
- 6. causation is when a change in one quantity causes a change in a second quantity
- 7. shows the relationship between two changin
- 8. the rate of change is the slope of the line
- 9. parallel lines are lines in the same plane that never intersect.
- 11. a direct variation is a relationship that can be represented by a function in the form y=kx=0.
