As the variable x increases, the variable increases and the slope also increases. The value
of the slope is 0.71.
o
What do the x-intercept and y-intercept represent in terms of the units on the
axes?
The analysis of the relationship between the variables X and Y can be determined by putting
them on a graph with intersection in X and in Y.
o
Identify the dependent variable and independent variable in terms of the units on
the axes.
The independent variable is in the intercept of X which is income. The dependent
variable is at the Y-intercept, which is happiness.
o
What is the correlational relationship between the two variables?
In conclusion, it can be determined that there is a correlation between income and
happiness. This can be determined by the fact that as the variable X increases, the
variable y increases. And because the slope is positive.
