The slope of the trend line is 0.90 ($900), which represents an increase in salary of $900 for every $1,000 increase in annual tuition cost. (Third Option).

Recall:

  • Slope of a trend line usually depicts a unit rate between two variables.
  • The equation of a trend line is usually represented in slope-intercept form as, y = mx + b.
  • Where, m is the slope, x and y are the two variables that are changing, while b is the initial value.

Given the equation representing the trend line as, s = 0.90c + 26.4

The slope of the trend line would be 0.90, which is $900.

This means that, there is an increase in salary of $900 for every $1,000 increase in annual tuition cost. (Third Option).
