Y = mx + b
m is your slope AKA rate of change
b is the y intercept.
from the graph we can see that the y intercept (b) is 15. (look at the y axis and see what point the line crosses on the y, here it is 15, in-between 10 and 20)
slope is rate of change. to figure this out remember slope = rise over run:

so pick two points. how much does one point rise after the other point you picked? In the graph it rises 1 square so rise = 1
Now looking at the same two points, how far away from each other are they on the x axis? Looking at the graph they are 2 squares away from each other. so run = 2
Now plug these numbers into the rise over run formula:

Now we have everything we need to put into our formula for a line:


For number 16 you should get:

after you do the same steps again yourself
Answer:
x = 
Step-by-step explanation:
4x-y+2z = 8x+y-4
4x-8x-y+2z = 8x - 8x +y-4
-4x -y +2z= y-4
-4x -y+y +2z = y+y-4
-4x +2z = 2y-4
-4x+2z-2z = 2y-2z-4
-4x = 2y-2z-4
= 
Answer:
$218
Step-by-step explanation:
$100 times 100% = $200
9% of 200 = 200X.09 = 18
200 + 18 = 218

Thank u so much have a good day too
Answer:
<
<
< 2.5
Step-by-step explanation:
Given the following numbers,
, let's express each as whole or decimal numbers, to find out the least to the greatest.


≈ 2.2
2.5 (already in decimal form)
≈ 1.7
From the least to the greatest, we have:
<
<
< 2.5
