Plot 1.5 and 1.9 on the number line to find which
inequalities are true. Check all that apply.

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.

Math it's appreciated. (picture provided)

3x + 4y = 5 x- 3y = -7 solve by substitution
