Directions: Using the integers 0-9 (without repeating any number), create 4 points that could generate a line of best fit with the equation y=-x+8.

(___,___) (___,___) (___,___) (___,___)

### Hint

What is the relationship between points and a line of best fit?

What are some other sets of integer pairs?

Question about the 2 solutions. When I type y = -1 + 8 into desmos and then plot both solutions, all 4 points are symmetrically spaced around this line. But for both solution sets, if I tell desmos to create the line of best fit y1 ~ mx1 + b I’m given y = -0.6x + 7.4 and y = -0.7 + 7 for the 2 data sets. Can anyone explain why that is?
