First we need to find the slope:
Slope formula=
Plug in your given values from the coordinate
Slope =
When we have 2 "-"'s together they turn into a + sign so we add.
Slope =
Slope =
Simplify (in this case divide) the slope:
Slope =
slope-intercept form is:
y=mx+b
Where m=slope
b=y-intercept
So far we have:
y=2x+b
To find b all we have to do is pick any given coordinate and plug it in:
I chose (3,1)
so we plug that in the equation
1=6+b
Now solve for b:
1=6+b
subtract 6 from both sides
b=-5
Final answer:
y=2x-5 (D)

Answer:
Add 3 times row 1 to row 2 to obtain the new matrix
Step-by-step explanation:
Attached below is the solution
To obtain the new matrix we will add 3 times Row 1 to row 2
original matrix
New Matrix
For this case, the first thing we must do is define variables.
We have then:
x: governor of a state gains
y: governor of b state earnings
We now write the system of equations that models the problem.
We have then:
Solving the system of equations we have:
Then, for x:
Answer: governor of a state earns $ 170395
governor of b state earns $ 115770
