Answer:
y = -0.25x - 6
Step-by-step explanation:
You can either just read off the slope m = -0.25 and the intersection with the vertical n = -6 or you form a system of equations from points you choose on the graph. For example:
(0,-6);(4,-7)
The general equation for a line:
y = m*x + n
The two points on the graph form a system of two equations:
1. -6 = m*0 + n
2. -7 = m*4 + n
You can read off n right away fro equation 1:
n = -6
Plugging n into equation 2:
-7 = m*4 - 6 => -1 = m*4 => m = -1/4
Answer:
thats alot of people don't you think
Step-by-step explanation:
45, 51, 52, 58, 61, 63, 66, 72, 74
You're trying to find the second quartile (Q₂), and to find that, you must find the median, and then find the median within the second half of the median :)
Median (Middle Number) : 61
Now, look at 61, and look at 74. What is the median of those numbers in this set?
Q₂ = 66
So, your quartile 2 is 66.
