Answer:
a. or 
Step-by-step explanation:
Slope is equal to y1-y2 over x1-x2.
So the equation would be:

2-(-1)=2+1=3
-3-(-1)=-3+1=-2
So the answer is:

The answer to the question is D
Answer:
1 2⋅−1⋅3 5=4 5
Step-by-step explanation:
Combine multiplied terms into a single fraction
12y−1⋅35=45
\frac{1}{2}y-1 \cdot \frac{3}{5}=\frac{4}{5}
21y−1⋅53=54
12−1⋅35=45
Use the x and y values from your point and the h and k from the center to write the equation you need to solve for r. The general form of the equation for a circle is

. We will fill in accordingly:

. Solve for r to get that
Answer:
10 losses
Step-by-step explanation:
Here, we want to get the greatest possible number of games the team lost
Let the number of games won be x
Number drawn be y
Number lost be z
Mathematically;
x + y + z = 38
Let’s now work with the points
3(x) + 1(y) + z(0) = 80
3x + y = 80
So we have two equations here;
x + y + z = 80
3x + y = 80
The greatest possible number of games lost will minimize both the number of games won and the number of games drawn
We can have the following possible combinations of draws and wins;
26-2
25-5
24-8
23-11
22-14
21-17
21-17 is the highest possible to give a loss of zero
Subtracting each sum from 38, we have the following loses:
10, 8, 6, 4, 2 and 0
This shows the greatest possible number of games lost is 10
