## Example Slope of a Line Graph A line passing through (0, -2) and (3, 4) Slope = (y2 - y1) / (x2 - x1) = (4 - (-2)) / (3 - 0) = 6/3 = 2 ## Example Slope of a Line Graph The graph shows the cost of candy as a function of the weight of the candy. Calculate the slope. * $3 for every ounce of can...

## Example Slope of a Line Graph A line passing through (0, -2) and (3, 4) Slope = (y2 - y1) / (x2 - x1) = (4 - (-2)) / (3 - 0) = 6/3 = 2 ## Example Slope of a Line Graph The graph shows the cost of candy as a function of the weight of the candy. Calculate the slope. * $3 for every ounce of candy bought * $0.38 for every ounce of candy bought * $2.66 for every ounce of candy bought * $0.50 for every ounce of candy bought ## The graph shows the height of a candle *y* after burning for *x* number of minutes. What is the rate at which the candle is burning? Select two points (-4, -4) and (8, 4) m = (y2 - y1) / (x2 - x1) = (4 - (-4)) / (8 - (-4)) = 8 / 12 = 2 / 3. 1 inch every 10 minutes x = 10
