Question 138051: How do I solve:
Find the equation of the line that contains the points whose coordinates are (9,-3) and has a slope of -1/3.
I lost my x somewhere
y-y1=m(x-x1)
Y-(3)=-1/3(x-9)
y-(-3)+ -1/3x(9)
-3= -3
Where did I go wrong?

Question 138485: Ok..i dont know if anyone can help me with these, but please..i need help.
Solve the systemof equations by graphing. Then classify the system as consistent or inconsistent and the equations as dependent or independent.
x + y = 13
x - y =3
What is the solution of the system of equations? (Type an ordered pair. type N if there is no solution. Type R if the solution is all real numbers)
Is the system consistent or inconsistent
Are the equations dependent or independent.
