Explanation
To solve the question, we will need to get the slope of the line
Thus, the slope will be
[tex]slope=\frac{change\text{ in y}}{change\text{ in x}}=\frac{30-12}{40-15}=\frac{18}{25}=0.72[/tex]
Since our slope is positive, then we are left with two options
Also, the y-intercept is positive
Considering the two options again, we will have both slopes and intercept as positive
Therefore, the answer will be
