What does the slope represent?
| 
 the rate at which the X variable changes as a result of the Y variable  | 
| 
 the rate at which the Y variable changes as a result of the X variable  | 
| 
 the rate at which the dependent variable changes as a result of the fixed cost component  | 
| 
 the rate at which the independent variable changes as a result of changes in the dependent variable  |

What does the slope
represent?
.
| 
 the rate at which the X variable changes as a result of the Y variable  | 
| 
 the rate at which the Y variable changes as a result of the X variable  | 
| 
 the rate at which the dependent variable changes as a result of the fixed cost component  | 
| 
 the rate at which the independent variable changes as a result of changes in the dependent variable  | 
.
Ans: the rate at which the Y variable changes as a result of the X variable
.
**Because the slope represents the rate of change in y as x changes. Because y is dependent on x, the slope describes the predicted values of y given x
.
**Here the Y dependable variable and X is in-dependable variable
.
The cost function is = Y = a + bx
Y = slop intercept, which mean here total cost
b = Slop of coefficient = variable cost
X = activity level = in-dependable variable
.
**Here all other options are wrong
.**It is used in the regression analysis
