State a true conclusion. 1) if two planes intersect, their intersection is a line. 2) plane r and plane s intersect. conclusion:

Two planes that intersect are simply called a plane to plane intersection. When they intersect, the intersection point is simply called a line.

Therefore, Plane R and Plane S form a line when they intersect.

The answer is "the intersection is a line".

Step-by-step explanation:  The concept of lines and planes that we studied in geometry are familiar to us. For example-

(i) The intersection of two lines is a point.

(ii) A plane consists of a line and a point not on the line, etc.

Like these, we have another fact that suppose there are two planes. Then we have two options

(a) They do not intersect with each other.

(b) If they do so, then their intersection is a line.

See the attached figure, there are two planes P and Q, which intersect at the line AB.

Since the given two planes intersect, the using the above fact we can say that their intersection is a line.  

Thus, the conclusion is "the intersection of two intersecting planes is a line."

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
