Answer:

Step-by-step explanation:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!

Answer:

Raul's claims are not correct

The equation of the graph is $y=\frac{10}{15}x$

Step-by-step explanation:

Part a)

we know that

The fact that the data form a straight line does not imply that it is a proportional relationship. In order for it to be a proportional relationship, in addition to the fact that a straight line must be formed, it must pass through the origin.

In this problem the graph shows a proportional relationship because the data forms a straight line and passes through the origin (0,0)

therefore

The claim that the graph shows a proportional relationship because the data forms a straight line is not correct

Part B)

<u>Find the slope of the straight line</u>

Let

$A(0,0),B(15,10)$
