Zestimate($ thousands) Selling Price($ thousands) 291.5 268 320 305 371.5 375 303.5 283 351.5 350 314 275 332.5 356 295 300 313 285 368 385

The graph below, called a scatter diagram, shows the points ( 291.5 , 268 ) , ( 320 , 305 ) , ... , ( 368 , 385 ) in a Cartesian plane.

From the graph, it appears that the data follow a linear relation.

Chapter F, Problem 3CP,

The graph below, called a scatter diagram, shows the points in a Cartesian plane.
From the graph,

Interpret the slope of the line.

Pick two points from the scatter diagram. Treat the zestimate as the value of x and treat the selling price as the corresponding value of y . Find the equation of the line through the two points you selected.
