Question

Which of the following points lie in the solution set to the following system of inequalities?

y x - 5
y -x - 4

Answer 1

Looks like the question is incomplete. However, the basic method is to solve the system and then you know where the lines intersect. If this is actually:

\(y=x-5\)
\(y=-x-4\)

You can do this:

\(x-4=x-5\)

Then solve for x, put x into either of the first equations and solve for y.
