Question
If a carpenter earned $1000, what is the best estimate for how many days he worked?
- 3
- 4
- 5
- 6
Hint:
Scatter plots are the graphs that present the relationship between two variables in a data-set. It represents data points on a two-dimensional plane or on a Cartesian system. The independent variable or attribute is plotted on the X-axis, while the dependent variable is plotted on the Y-axis.
The correct answer is: 4
If a carpenter earned $1000, by plotting the line on x axis he works 4days to earn $1000.
