Hey there! I'm happy to help!
The median is the line cutting the triangle in this graph. In general, a median connects any of the triangle points to halfway across the side opposite to that point. This median connects R to halfway across the side across from R.
We want to find the equation of this median. We see that T is at (-2,3) and R is (3,-3). The first thing to do when looking for the equation of the line is to find the slope, or incline. Since we have two points, we can do this very easily. You simply divide the difference in the y-values by the difference in the x-values.
DIFFERENCE IN Y-VALUES
3-(-3)
3+3
6
DIFFERENCE IN X-VALUES
-2-3
-5
Now, we divide the two answers, giving us -6/5.
So, we have our slope, which gives us the equation so far y=-6/5x+b. We just need to find the b, which is our y-intercept. Well, to do this, we plug in one of our points and we can solve for b. We will use (3,-3)!
-3=-6/5(3)+b
-3=-3 3/5+b
We add 3 3/5 to both sides to isolate the b.
b=3/5
This means that this median should hit the y-axis at (0,3/5), and it looks like it does. Therefore, the equation of this median is y=-6/5x+3/5.
Now you can find the slope of a median! Have a wonderful day! :D

first find the area of the rectangle (12x16)
then, the confusing part, pretend the semicircle is a full circle and find the area and divide by 2
add the two up and put 
and that should be it
Answer:
The area of the second rectangle will be 36 square centimetres
Step-by-step explanation:
Given:
Area of the first rectangle = 4 square centimetres
A second rectangle is 3 times as long and 3 times as wide as the first rectangle
To Find:
Area of the second rectangle = ?
Solution:
We know that area of the rectangle is Length X breadth
Length X width = 4
In this case the are 2 possibilities
Case 1:
Length = 2 cm
Width = 2 cm
2 X 2 = 4
Now According to the question
Length is 3 times = 2 X 3 = 6cm
width is also 3 times = 2 X 3 = 6 cm
Now the area of the second rectangle will be
6 X 6 = 36 square centimetres
Case 2:
Length = 4 cm
Width = 1 cm
4 X 1 = 4
Now According to the question
Length is 3 times = 4 X 3 = 12 cm
width is also 3 times = 1 X 3 =3 cm
Now the area of the second rectangle will be
12 X 3 = 36 square centimetres
