If a linear function has a negative slope, what does this indicate about the relationship between the independent and dependent variables?
They have a negative correlation
In a linear function where b = 0, what characteristic of the function is highlighted?
The linear function is a constant function
If in a linear function, the slope 'b' is greater than 1, how would you describe the relationship between the variables?
The dependent variable increases at a faster rate than the independent variable
If the y-intercept 'a' in a linear function is negative, what does this imply about the relationship between the variables?
The dependent variable decreases when the independent variable increases
