Answer:

0.4x+2

Step-by-step explanation:

Answer:

  • y = 0.4x + 2

Step-by-step explanation:

Use two pairs of points from the table:

  • (4, 3.6), (5, 4)

The function in slope-intercept form:

  • y = mx + b

Find the slope:

  • m = (4 - 3.6)/(5 - 4) = 0.4/1 = 0.4

Use one of the points and find the y-intercept:

  • 4 = 0.4*5 + b
  • b = 4 - 2
  • b = 2

The line is:

  • y = 0.4x + 2
