Question

(b) Hilda uses the function y = 0.0005x + 60 to model the situation. What score does the model predict for a salary of $65,000?

(c) What does the number 0.0005 in Part (b) mean in the context of the situation?

Answer 1

Based on the given, the model follows a straight line with a slope-intercept form with the equation y=0.0005x + 60. At a $65000 salary, it obtained a score of 92.5. This is obtained by substituting to x in the given equation. For part (c), 0.0005 is the slope of the line.
