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.

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.
