Determine whether the ordered pair is a solution of the inequality
(5, 12); 6y-7x.7
Is the ordered pair a solution of the inequality? no or yes
solve the system of equations by graphing. Then classify the system as consistent or inconsistent and the equations as dependent or independent.
6x-y=33
6x+7y=9
What is the solution of the system of equations?

Is the system consistent or inconsistent?

In the first question, you do not provide an inequality. 6y-7x.7 is not an inequality.

In the second question, the equations are independent. Suntract the first from the second and you get 8y = -24, so
y = -3 and 6x = 30, so x = 5.
