(a) "PayRate" = 1/2 xx "YearsOfExperience" + 8 " dollars"
(b) "Predicted Pay Rate After 14 Years" = $15"/hour"

Explanation:

This looks as if it is a linear relation with

  • y pay (in dollars per hour) at about 8 for x (years of experience) equal to 0; and
  • rising to about y=18 when x=20.

This would give an equation with a y-intercept of 8 and
a slope of (Deltay)/(Deltax)=(18-8)/(20-0)=10/20=1/2

The slope-intercept form of the equation would be:
(a)color(white)("XXX")y = 1/2x+8

For an employee with x=14 years of experience, this would give a predicted hourly rate (in dollars):
(b)color(white)("XXX")y=1/2 * 14 + 8 =15
