Question 6 Multiple Choice Worth 5 points)

Mathematics
1 answer:
Citrus2011 [14]3 years ago

Answer:

The equation of the graph is;

y = 4·x

Step-by-step explanation:

The coordinates of two points, (x₁, y₁), and (x₂, y₂) respectively on the straight line graph are;

(-3, 12), and (2, 8)

The slope, m, of the straight line graph is given as follows;

Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}

Therefore, by substitution of the values, we have;

Slope, \, m =\dfrac{8-(-12)}{2-(-3)} = \dfrac{8 + 12}{2 + 3} =\dfrac{20}{5}  = 4

The equation of the graph in point slope form is therefore;

(y - 8) = 4×(x - 2)

y = 4·x - 8 + 8 = 4·x

y = 4·x.

All of the following are rational except _____.
r-ruslan [8.4K]

Answer:  Option 'A' is correct.

Step-by-step explanation:

Since we have given that

Rational numbers are those numbers which can be written as p/q form or it must be non terminating but recurring number.

-13 can be written as p/q form as \dfrac{-13}{1}

\dfrac{14}{5} is a rational number because of its form.

81 can be written in p/q form as \dfrac{81}{1}

But √2 is non terminating and non recurring number.

Hence, √2 is not a rational number.

Therefore, Option 'A' is correct.
