I'll do the first one to get you started

d)



Start with the given system of equations:





In order to graph these equations, we must solve for y first.


Let's graph the first equation:


Start with the first equation.


Subtract from both sides.


Divide both sides by to isolate .


Rearrange the terms and simplify.


Now let's graph the equation:


Graph of .


Note: let me know if you need help graphing equations

-------------------------------------------------------------------


Now let's graph the second equation :

Graph of .


-------------------------------------------------------------------


Now let's graph the two equations together:


Graph of (red). Graph of (green)


From the graph, we can see that the two lines intersect at the point . So the solution to the system of equations is . This tells us that the system of equations is consistent and independent.
