Scatter Plots & Trend Lines

y = 3x

y = 4x - 2

y = -5x

y = -2x - 4

The relationship is not linear.

$$y=\frac{10}{3}x+20$$

$$y=\frac{3}{10}x\ +\ 20$$

$$y=\frac{1}{3}x\ +\ 20$$

$$y=3x\ +20$$

$$y=x+0$$

$$y=25x$$

$$y=25x\ +\ 250$$

$$y=50x$$

True; the equation is y = 2500x -125

False; the equation is y = -250x + 2500

False; the equation is y = 2500x - 250

False; the equation is y = -125x + 2500

True
