Question

The graph above shows a plot a data set. We know that the slope of the line of best fit is - 1/5. What vertical changeneeds to be applied to the function y = 1/5x to make the linear function best model the data set?A) a vertical change of down 5 unitsB) a vertical change of up 6 unitsC) a vertical change of up 5 unitsD) a vertical change of down 1/5 units

Answer 1

C) y=-1/5x +5

1)Since the function y=-1/5x is a decreasing line, that crosses the origin.

Then the needed transformation the best fits the data set would be a vertical change up of 5 units.

2) Above the parent function y=-1/5x and y=-1/5x +5
