The slope 0.90, as it relates to the trend line signifies that, there is a $900 increase in salary for every $1,000 in annual tuition costs. (Choice C).

Recall:

  • Equation that models a trend line is expressed in slope-intercept form as, y = mx + b
  • The slope = m
  • y and x are the two variables, wile b is the initial value.

Thus, given that equation that models the trend line in the scatterplot given is, s = 0.90c + 26.4

The slope is therefore, 0.90, which is $900.

  • The slope 0.90, as it relates to the trend line signifies that, there is a $900 increase in salary for every $1,000 in annual tuition costs. (Choice C).
