A. correct as it is
B. 5, 4, 3, 0
y = -2x + 3....slope = -2, y int = 3
2x + 4y = 8
4y = -2x + 8
y = -1/2x + 2....slope is -1/2, y int is 2
this is graph C
Part A:
Six Tents Holds 42 People
Nine Tents Holds 63 People
10 Tents Holds 70 People
Part B:
Number of tents|||Number of people
1 |||7
6 |||42
9 |||63
10 |||70
Part C:
Tents=x
1x=7 people

<h2>
Explanation:</h2>
The complete question is attached below. In order to solve this problem, we'll use a graphing tool. First of all, we'll say that the LHS is a linear function and the RHS is another linear function, so for each case, we'll have:

For each graph,
will be drawn in red while
will be drawn in blue.
Case 1:

So by equating both equations:

By using graphing tool we get a point of intersection at which the x-value is the solution to our equation. So:
<u>Solution:</u>

See First Figure below.
Case 2:

Applying a similar method as in case 1.
<u>Solution:</u>

See Second Figure below.
Case 3:

Applying a similar method as in case 1.
<u>Solution:</u>

See Third Figure below.
Case 4:

Applying a similar method as in case 1.
<u>Solution:</u>

See Fourth Figure below.
