For the function whose graph is shown, the correct formula for the function would be option A; y = -2x+3.
<h3>What is the slope?</h3>
The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
Here, y-intercept is at positive 3,
so the value of b is +3
The line is going downward from left to right, so the slope will be negative.
The slope is defined as rise over run,
= 2/1, = 2,
So the "m" value is -2.
This will gives the functions equation to be
y = mx + b
y = -2x + 3.
Hence, For the function whose graph is shown, the correct formula for the function would be option A; y = -2x+3.

Answer:
12(5+3)
Step-by-step explanation:
Again, <u>common </u>greatest number is 12. Just try out numers until its the highest common number.
60/12 = 5
36/12 = 3
so,
12(5+3)
Answer: choice A
---------------------------------------------------------------------
---------------------------------------------------------------------
Work Shown:
P(TV) = (number who watch tv)/(number total)
P(TV) = 30/100
P(TV) = 0.30
P(Girl) = (number of girls)/(number total)
P(Girl) = 55/100
P(Girl) = 0.55
P(TV)*P(Girl) = 0.30*0.55 = 0.165 which rounds to 0.17
We'll use this value later. So let's call this M = 0.17
Look in the "girl" row and "tv" column. The value 17 is here.
This is out of 100 people total, so
P(TV and Girl) = 17/100 = 0.17
Call this value N = 0.17
Because M = N = 0.17 approximately, this means that the two variables "TV" and "Girl" are approximately independent
So the equation P(TV and Girl) = P(TV)*P(Girl) is approximately true in this example.
This points to choice A being the answer.
