Question #5ab04

Answer 1

(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`
