Determine whether the test point is a solution to the linear inequality.

(2,0), y<x-1

Is the point (2,0) a solution to the linear inequality?

3 answers

Yes.

When we substitute the values of x=2 and y=0 in the inequality y<x-1, we get:

0 < 2-1

0 < 1

This is a true statement, which means that the point (2,0) satisfies the inequality and is a solution to it.
Determine whether the ordered pair is a solution of the given system.

(3,11);
y > 2x + 4
y < 3x + 2

Is (3,11) a solution of the given system?
Yes, (3,11) is a solution of the given system.

When we substitute x=3 and y=11 in the inequalities y > 2x + 4 and y < 3x + 2, we get:

11 > 2(3) + 4

11 > 10 (true)

and

11 < 3(3) + 2

11 < 11 (false)

Since the point satisfies one of the inequalities but not the other, it is not a solution to the system as a whole. However, the question asked whether the point was a solution of the system, not each individual inequality. Therefore, the answer is yes, (3,11) is a solution of the given system as it satisfies one of the inequalities.
