Hi.
To formally answer your question:
D. y = 0.75<em>x</em> + 11
We can prove this by substituting <em>x</em> with 1 (the initial measurement)
y = 0.75(1) + 11 = 11.75

Answer:
-6/8
Step-by-step explanation:
The rate of change is the same as the slope (I don't know if you have learned that term yet), but basically its the change in y's over the change in x's. to find this out, all you have to do is count from the point on the graph that is the farthest right (in this case, (6,1)), up to the y coordinate of the point farthest to the left (-2, 7) which is 6, and then count the number of spaces between the x coordinates, which is 8. put the rise (up and down count) over the run (horizontal count) in a fraction form, which gives you 6/8, and then notice how the line is pointing towards the bottom RIGHT hand corner making the line negative, so you need to make the rate of change negative, giving you the final answer of -6/8.

Answer
a) k=7, h=9, the unique solution of the system is 
b) If k=6 and h=8 the system has infinite solutions.
c)If k=6 and h=9 the system has no solutions.
Step-by-step explanation:
I am assuming that the system is x1+3x2=4; 2x1+kx2=h
The augmented matrix of the system is ![\left[\begin{array}{ccc}1&3&4\\2&k&h\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%263%264%5C%5C2%26k%26h%5Cend%7Barray%7D%5Cright%5D)
. If two times the row 1 is subtracted to row 2 we get the following matrix![\left[\begin{array}{ccc}1&3&4\\0&k-6&h-8\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%263%264%5C%5C0%26k-6%26h-8%5Cend%7Barray%7D%5Cright%5D)
.
Then
a) If k=7 and h=9, the unique solution of the system is 
and solviong for 
,
Then the solution is
b) If k=6 and h=8 the system has infinite solutions because the echelon form of the matrix has a free variable.
c)If k=6 and h=9 the system has no solutions because the last equation of the system of the echelon form of the matrix is
