10-12.

Multiple Choice: Which of the points below is a solution to $y < | x - 3 |$ ?

Hint:

Test each point in the inequality to see if it makes the inequality true.

$\left(2,1\right)$
Help (a):
$1<|2−3|\\1<|−1|\\1<1$
The resulting inequality is not true because $1$ is not less than $1$ .
Therefore $\left(2,1\right)$ is not a solution.

$\left(-4,5\right)$

$\left(-2,8\right)$

$\left(0,3\right)$
