Question 2
As far as I can see, you got it right. The general transformation for 90 ccw is 
(x,y) ===> (-y, x)
What that means is for the x you put in -y changing the sign to the opposite and for the y you put in x and this time you leave the sign alone . The transformation is shown in the left hand diagram.
The two tables are shown below.
Original
The transformed table is
- (-4,1)
- (-2,1)
- (-2,3)
- (-5,3)
- (-4,1)    This is just to let the program know to close the figure For some reason this did not have lines and if I delete it and put the lines in, I won't be able to upload the new diagram.
===========
Four
This one transforms from (x,y) to (-x,-y) which means where you see an x, you put a - x and where you see a y, you put a minus y. It is the middle frame.
Original
- (-4,3)
- (0,3)
- (-2,0)
- (-4,3)  Here again, this is just to close the figure.
The transformed figure in red I think is
- (4,-3)
- (0,-3
- (2,0)
- (4,-3) And this closes the figure as well.
==========
Six
The diagram is on the right
Reflection about the y axis. Here the transformation is (x,y) ====> (-x,y) notice the ys don't change.
There is no closure.

Answer:
5
Step-by-step explanation:
Remember, the rank of a matrix is the number of pivots or number of rows different of zero in the echelon form of the matrix.
Then, if A is a matrix  the maximum number of pivots that can have is one by row, that is, 5.
 the maximum number of pivots that can have is one by row, that is, 5.
Then the maximum rank that A can have is 5.
 
        
             
        
        
        
        
Answer:
Your answer will be 
y=2x-15.5
Step-by-step explanation:
Hi, there you must know the slope-intercept form which is 
y=mx+b
m=slope
b=y-intercept 
You can also use
the slope formula which is 

in this case
it will look like this
 =
= =-2
=-2
So the slope is -2 
Now we will find the y-intercept 
-7.5=2(4)+b
-7.5=8+b   Subtract 8 both sides
-15.5=b
Your y-intercept is -15.5
Hope this helps
