- 3x+y=8--(1)
2x+4y=12
- x+2y=6--(2)
- (1)×1 and (2)×3
Subtract both
Put the value in eq(2)
The line drawn for a scatter plot may not always be the line of best fit. But you can change it to a line of best fit by adjusti
ng its y-intercept and
slope. In this activity, you will change lines to better fit the data.
Part A
How could you change the slope and the y-intercept of the line in this graph to better fit the data? (Hint: Visualize what the best fit line would look
like, and then describe how to transform the existing line to that one.)
