Question
The slope is zero means
- horizontal line
- positive correlation
- negative correlation
- vertical line
The correct answer is: horizontal line
The slope is zero means a horizontal line..
When there is no change in dependent variable with change in independent variable the slope of line becomes zero and line is parallel to x axis
Correct option is (a).
when slop of any equation is zero it means there is no change in dependent variable with change in independent variable hence the graph becomes a horizontal line

The scatter plot shows David’s height at various ages. Choose the right answer that describe the type of association between David’s age and his height.
The corerect option is (c)
Reason :
As the height of David increases with increase in his age , the graph is going upward as both the variable are increasing so it is a case of positive association and since there is almost constant change in both the variable it is shows linear relationship also
