Answer:
No need for tool
With Two points is enough to describe this graph
![\left[\begin{array}{cc}(-20)/(3) &0\\0&120\end{array}\right]](https://img.qammunity.org/2020/formulas/mathematics/middle-school/fz829xj71d81ik2er39a83mkupdc8sp98y.png)
Explanation:
Interception with Y axis (y=0), thus we have the following equation:


since we can not simplify much more
The point for this is (-20/3 , 0)
Interception with x axis (x=0), thus we have the following equation:


The point for this is (0, 120)
