Graph y=8.5xy=8.5xy, equals, 8, point, 5, x.

Morgarella [4.7K]

Answer:

A, B, E

Step-by-step explanation:

<u>Given equation</u>

y = 8.5x

<u>Answer choices</u>

A. The equation represents a proportional relationship.

TRUE, it is in the form of y = kx

B. The unit rate of change of y with respect to x is 8.5

TRUE, y = mx + b, the slope m = 8.5 is the rate of change

C. The slope of the line is 2/17

False, the slope is 8.5

D. A change of 17 units in x results in a change of 2 units in y.

False, a change of x = 17 results in 17*8.5 = 144.5 units in y

E. A change of 4 units in x results in a change of 34 units in y.

TRUE, because 4*8.5 = 34

4. Which of the following lines is perpendicular to y = -2X + 8?

Alenkinab [10]

For this case we have to by definition, if two lines are perpendicular then the product of its slopes is -1.

That is to say:

$m_ {1} * m_ {2} = - 1$

We have the following equation:

$y = -2x + 8$

So:

$m_ {1} = - 2$

Thus:

$m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {- 2}\\m = \frac {1}{2}$

Thus, a line perpendicular to the given line must have slope $m = \frac {1} {2}.$

Option A:

$x + 2y = 8\\2y = -x + 8\\y = - \frac {1} {2} x + 4$

It is not perpendicular!

Option B:

$x-2y = 6\\2y = x-6\\y = \frac {1} {2} x-3$

If it is perpendicular!

Option C:

$2x + y = 4\\y = -2x + 4$

It is not perpendicular!

Option D:

$2x-y = 1\\y = 2x-1$

It is not perpendicular!

The correct option is option B

ANswer:

Option B
