Again, (-3,2) must be the interval notation for -3%3Cx%3C2; otherwise the question makes no sense.

The given EQUATION is 3x%2B5=1;
3x=1-5
3x=-4
x=-4%2F3

THAT is the solution of the equation. The given interval contains the solution but it is a set of points with only one value being a solution to the given equation. The given interval IS NOT THE SOLUTION.

Your question makes no sense whatsoever. You ask if a particular ordered pair is a solution of some set of (presumably) two-variable inequalities, but you don't provide any inequalities. Then you provide a single variable equation.

In general, to determine if a particular ordered pair is an element of the solution set of a two-variable inequality, substitute the x-coordinate of the ordered pair in place of the x-variable in the inequality, then substitute the y-coordinate of the ordered pair in place of the y-variable. Do the indicated arithmetic.

If the result is a true statement, then the ordered pair IS an element of the solution set. Otherwise, not.
