Question

Max is given the graph of the linear
inequality and asked
to determine whether a given point is
a solution. She notices that the point
falls on the boundary line of the
graph. What should she conclude?
(1 point)
3x − 7.2y < 0
The point is a solution to the
linear inequality because
points on boundary lines are
only solutions when the
inequality symbol is > or <.
The point is not a solution to
the linear inequality because
points on boundary lines are
only solutions when the
inequality symbol is ≥ or ≤.
The point is not a solution to
the linear inequality because
points on boundary lines are
never solutions to linear
inequalities.
The point is a solution to the
linear inequality because
points on boundary lines are
always solutions to linear
inequalities.

Answer 1

The point is not a solution to the linear inequality because the inequality is strict (<). Points on the boundary satisfy 3x − 7.2y = 0, so they're only included when the inequality is ≥ or ≤, not when it's < or >.
