Answer:

  • A. y=0.5x + 23

Step-by-step explanation:

Take two random pairs from the table and find the formula:

  • (12, 32) and (24, 36)

Find the slope:

  • m = (36 - 32)/(24 - 12) = 4/12 = 1/3

Find y-intercept:

  • 12*1/3 + b = 32
  • b = 32 - 4 = 28
  • b = 28

The line is:

  • y = 1/3x + 28

The best fit is A. y = 0.5x + 23, the other options have too much of difference in the slope or y-intercept
