There is only one graph but if you have to make an equation rule it will be y= 80x+ 270

Answer:

<h2>First graph.</h2>

Step-by-step explanation:

We can define the linear function: y=80x+270, which model the situation.

One effective and certain way to find the correct graph is graphing the function as it is. For that purpose, we just have to find to points and draw the line. The most common point for a linear function are the interceptions with each axis, that is, when x=0 and y=0. For the first case, when x=0, we have:

y=80(0)+270=270

For y=0, we have:

0=80x+270

-270=80x

x=\frac{-270}{80}=-3.4

So, the interception-axis points are: (0;270) and (-3.4;0)

The faster way to find the right graph is observing which one has axis-interceptions at his points.

We observe that the first graph has this point as interception:

x-axis interception: (-3.4;0)

y-axis interception:(0;270)

Therefore, the first graph is the right answer.

All about simulitious equations​
Korolek [52]

Answer:

On occasions you will come across two or more unknown quantities, and two or more equations

relating them. These are called simultaneous equations and when asked to solve them you

must find values of the unknowns which satisfy all the given equations at the same time.

Step-by-step explanation:

1. The solution of a pair of simultaneous equations

The solution of the pair of simultaneous equations

3x + 2y = 36, and 5x + 4y = 64

is x = 8 and y = 6. This is easily verified by substituting these values into the left-hand sides

to obtain the values on the right. So x = 8, y = 6 satisfy the simultaneous equations.

2. Solving a pair of simultaneous equations

There are many ways of solving simultaneous equations. Perhaps the simplest way is elimination. This is a process which involves removing or eliminating one of the unknowns to leave a

single equation which involves the other unknown. The method is best illustrated by example.

Example

Solve the simultaneous equations 3x + 2y = 36 (1)

5x + 4y = 64 (2) .

Solution

Notice that if we multiply both sides of the first equation by 2 we obtain an equivalent equation

6x + 4y = 72 (3)

Now, if equation (2) is subtracted from equation (3) the terms involving y will be eliminated:

6x + 4y = 72 − (3)

5x + 4y = 64 (2)

x + 0y = 8
