We have two points so we can find the gradient using y1-y2/x1-x2
gradient = 21-27/2-8
= 1
we know the form for any linear equation is y = mx + c
we have m and a point so we can substitute in point (2,21) to find c
21 = 1 x 2 + c
c = 19
therefore, the equation is y = x + 19

Y = x + 19


Slope(m) formula: y2 - y1 / x2 - x1
y2 - y1 / x2 - x1 = 27 - 21 / 8 - 2 = 6 / 6 = 1

y = mx + b
y = 1x + b or y = x + b (the one is usually invisible)

Now, we use either one of our points to find b. I will be using (2, 21).

y = x + b
21 = 2 + b
- 2 - 2
19 = b

y = x + b -> y = x + 19


Check your answer using either one of the points.

y = x + 19
21 = 2 + 19
21 = 21
This statement is correct


y = x + 19
27 = 8 + 19
27 = 27
This statement is correct

Therefore, our equation is: y = x + 19



Hope this helps!

Rewrite the following in the form log(c).<br> log(10) – log(5)
Svet_ta [14]

Answer:

log(2)

Step-by-step explanation:

In order to combine log(10) and log(5), you need to look at the sign that's combining them. In this example, it is a subtraction sign. When two logs are being subtracting from each other, it's the same as dividing the two. You would rewrite it like this:

log(10/5)

You would then solve 10/5, and get 2. You would rewrite the log as:

log(2)

Answer:

<em>The true statements are:</em>

<em>*The median weight for shelter A is greater than shelter B.</em>

<em>*The (IQR) interquartile range of shelter A is greater than the (IQR) interquartile range of shelter B.</em>

Step-by-step explanation:

<em>(for shelter A)</em>

median: 21

lowest value: 8

highest value: 30

lower quartile: 17

upper quartile: 28

(IQR) interquartile range: 28 - 17 = 11

Range: 30 - 8 = 22

<em>(for shelter B)</em>

median: 18

lowest value: 10

highest value: 28

lower quartile: 16

upper quartile: 20

(IQR) interquartile range: 20 - 16 = 4

Range: 28 - 10 = 18

~phew!, this took me long xd, hope this helps you~

I would highly appreciate it if you would mark me the brainliest~ :)
