Yes because each output (y) has a unique input (x).

Answer:Yes, it is definitely a function. Although one might say that it is not a one to one or injective function because of the presence of (-1,-2) and (6,-2).. The correct option among the two options that are given in the question is the second option. I hope that this is the answer that has actually come to your desired help

Answer:

y = -1/2x

Step-by-step explanation:

The y - intercept is 0, because the point where the line touches the y - axis is y - value of 0

The slope is -1/2 because as it rises by -10, it runs by 20

Slope is rise/run which is -10/20 which simplifies to -1/2

y = mx + b

b = y - intercept

m = slope

y = -1/2x + 0 or y = -1/2x

If my answer is incorrect, pls correct me!

Quadrilateral EFGH is on a coordinate plane. Segment FG is on the line 2x − y = −3, and segment EH is on the line 2x − y = 1. Wh

umka2103 [35]

Answer:

They have the same slope of 2 and are, therefore, parallel.

Step-by-step explanation:

Given: Equation of FG is $2x-y=-3$ and equation of EH is $2x-y=1$

To find: Relation between segments FG and EH

Solution:

Slope of a line describes its direction and the steepness.

Two lines are said to be parallel if their slopes are equal.

$2x-y=-3$

Differentiate with respect to x

$2-y'=0\\y'=m_1=2$

where $m_1$ denotes the slope of the line FG

$2x-y=1$

Differentiate with respect to x

$2-y'=0\\y'=m_2=2$

where $m_2$ denotes slope of line EH

As $m_1=m_2=2$ , lines are parallel

5/6 d = -15? I don't understand

Dahasolnce [82]

.

$\frac{5}{6} d = - 15$
First you have to simplify 5/6d to 5d/6 as shown below
$\frac{5}{6} d = \frac{5d}{6}$
Then multiple both sides by 6 because you are trying to solve for d
$5d = - 15 \times 6$
Multiply -15 and 6 to get -90
$5d = - 90$
Divide -90 by 5
$d = \frac{ - 90}{5}$
$d = - 18$
Then if you check it, it will give you -15 as your answer
$\frac{5}{6} \times - 18 = - 15$
$\frac{5 \times - 18}{6} = - 15$
$\frac{ - 90}{6} = - 15$
$- 15 = - 15$
