Solve the system of inequalities: y + 2x > 3 and y 3.5x − 5

Answers:
The first inequality, y + 2x > 3, is in slope-intercept form.:y > –2x + 3
The first inequality, y + 2x > 3, has a boundary line.:dashed
The second inequality, y 3.5x − 5, has a boundary line.:solid
Both inequalities have a solution set that is shaded their boundary lines.:above
is a point in the solution set of the system of inequalities.:(1, 5)
