Question | Answer |
---|---|
Direct Variation | An equation of the form y = kx, where k=0. |
Line of Fit | A line that describes the trend of the data in a scatter plot. |
Negative Correlation | In a scatter plot, as x increases, y decreases |
Parallel Lines | Lines in the same plane that never intersect and have the same slope. |
Perpendicular lines | Lines which meet to form right angles and whose slopes that are an opposite reciprocal. |
Point-slope Form | An equation of the form y - y1 = m(x - x1), where m is the slope and (x1, y1) is a given point on a nonvertical line. |
Positive Correlation | In a scatter plot, as x increases, y increases, or as x decreases, y decrease. |
Rate of Change | The change in a quantity over time. |
Scatter Plot | A graph that shows the general relationship between two sets of data. |
Slope | The ratio of the change in the y-coordinates (rise) to the corresponding change in the x-coordinates (run) as you move from one point to another along a line. Rise over run or y over x. |
Slope-intercept Form | An equation of the form y = mx + b, where m is the slope and b is the y-intercept. |
