Since ' x ' and '-x ' are both equal to ' y ', they must be equal to each other.

                                     x = -x

Add ' x ' to each side:     2x = 0

Divide each side by  2 :    <em>x = 0</em>
                        whence  <em> y = 0</em> .

That's the only possible solution to the system [ y = x  and  y = -x ] .

Since x and -x both equal y they must be equal to each other:
x= -x 
+x  +x (add x to both sides)
2x=0
x=0 
when x=0, y=0

Use the trend line to predict what the value of variable N will be when variable M equals 50.
ahrayia [7]

Answer:

N = 10

Step-by-step explanation:

Normally the coordinate system goes:

x axis (horizontal)

y axis (vertical)

Here, we have:

Horizontal axis as "M", and

Vertical axis as "N"

We want to know what N will be when M equals 50.

So, we look at the x-axis and go to M equals 50.

Then we move up until the "trend line". The intersection.

If we move directly left to vertical axis (N variable), we see that it is at the point:

N = 10

So,

When M = 50, N = 10
