Answer:
B=-1
Step-by-step explanation:
Standard form is Ax+By=C.
In this case, Ax is x, By is 1/5y, and C is +2.
To isolate the 2 (the C), subtract x from both sides of the equation:
x+2=1/5y
-x -x
2=-x+1/5y.
Now, the value of B, the x value, is -1.
C=pi(radius)^2
c=pi(5)^2
c=pi(25)
c=78.5398163397...
c is about 78.5

x=5
12-5=7
Answer:

Step-by-step explanation:
The point-slope form of the equation of a line is:
y - k = m ( x - h )
Where m is the slope and (h,k) is a point through which the line passes.
Given a line passes through points A(x1,y1) and B(x2,y2), the slope can be calculated with the equation:

We are given the points (-6,-9) and (7,7), thus the slope is:

Now we apply the point-slope formula using the point (-6,-9):

This equation is expressed in the required format
