Finding the Slope of a Trend Line

What ordered pairs would you use to find the slope for the trend line?

• (1,0) (6,8)

• (8,6) (0,1)

What ordered pairs would you use to find the slope for the trend line?

• (9,0) (3,8)

• (0,9) (8,3)

Find the slope between (1,0) and (6,8)

• m = -8/5

• m = 8/5

• m = 7/6

If m = 8/5 and b = -8/5, what is the equation of the trend line in y= mx + b?

• 0 = 8/5 (1) - 8/5

• y = -8/5 x + 8/5

• y = 8/5 x - 8/5

• y = mx + b
