Y = -4x + 2
3x + 2y = 6 (or in y-intercept form y=-3/2x + 3)

2x - y = 7 equals y = 2x -7 in y-intercept form. This means that the line has a positive slope and therefore goes upwards. This cannot be a potential equation because the line shown is clearly pointing downwards.

y=5 indicates that the line is a horizontal line that neither points upwards or downwards. This cannot be a potential equation because the line is pointing downwards.

The only possible equations left are y= -4x + 2 and 3x + 2y = 6, both of which graph a line pointing downwards because their slopes are negative. Hope this helps!

What is the median value of the data set shown on the line plot? Enter your answer in the box. A line plot with twenty-two data

Bogdan [553]

Answer: the median is 6.

Please see the picture attached.

A line plot shows the number of occurrences (crosses) of each number of a data set.

The median is the central value, the middle number, of a data set ordered from least to greatest. When there are two middle numbers, the median will be the mean between the two.

In order to find the median, look at the line plot: count how many values you have (22), then add 1 (23) and divide by two (11.5). Since we have an even number of values, we will have two middle numbers, which will be in the eleventh and twelfth position.

Count the crosses from the left, the eleventh and twelfth crosses both correspond to the number 6, therefore the median is 6.

You can also write all the numbers in increasing order and divide them into two equal groups:
1, 2, 3, 3, 4, 4, 5, 5, 5, 6, 6 | 6, 6, 7, 7, 7, 8, 8, 8, 9, 9, 11

The median will be the average between the two central numbers, therefore 6 (again).

Write the slope intercept equation of the function f whose graph satisifies the given conditions. The graph of f passes through

MrMuchimi

Let's find slope first.

(1,-2)
(-8,6)

$\\ \sf\longmapsto m=\dfrac{6+2}{-8-1}$

$\\ \sf\longmapsto m=\dfrac{8}{-9}$

Slope intercept form

$\\ \sf\longmapsto y=mx+b$

$\\ \sf\longmapsto y=-\dfrac{8}{9}x-2$

Correct I’ll give brainlist no links or I’ll report

Gwar [14]

Alright, to start, slope-intercept form is y=mx+b, where m is the rate is it going up/down by, and b is the starting point.

With this, the question says that Coraz started with 0 naxvips then purchased 10 each month afterwards.

From this, we can fill in the equation, using m as the rate it is going up/down and b as the starting point:

<h3>The Equation: </h3>

y=10x+0

Next, it wants a table, so let's use the equation created to do this. X is the amount of months that have gone by, deciding how many naxvips Coraz has purchased.

So, to start, lets plug in 0 months into the equation into x:

y=10(0)+0

y=0+0

y=0

The answer resulted in 0 for month 0, understandably. Month 0 was when it said Coraz had 0 naxvips on his farms. With this, it would be (0,0) for this part.

For the next month, same thing, just plug it in:

y=10(1)+0

y=10+0

y=10

The answer resulted in 10 for month 1. Month 1 was when it said Coraz purchased his first batch of 10 naxvips. With this, it would be (1,10) for this part.

Again, with 2 months

y=10(2)+0

y=10+0

y=20

The answer resulted in 20 for month 2. Month 2 was when he got another 10 naxvips. With this, it would be (2,10) for this part. However, see the pattern? For every month, there will be 10 more naxvips added. With this, we can write out the table for it as well:

<h3>The Table:</h3>

(X, Y)

0, 0

1, 10

2, 20

3, 30

4, 40

etc..
