- Slope formula:
Firstly, let's set up our equation. Place the two coordinates in the slope formula and have it equal 8: 
Next, combine like terms: 
Next, multiply both sides by 7: 
Next, add 4 onto both sides of the equation: 
Lastly, divide both sides by 2 and <u>your answer will be 
</u>
Answer:
Here is the complete question attached with.
The mean score would decrease more than the median score.
Step-by-step explanation:
The numbers for which we have to find the mean and median are:
Here the mean, 
Median,
as median is the middle term if the observations are arranged in ascending order.
Now as the question says that we have to add a zero to see its effect.
So adding a zero we have
Mean 
Median 
,as number of observations is even terms so we will add two middle numbers and divide it with 
.
So we can conclude that the mean is having more variation than the median.
Mean shows as variation of 
where as Median shows a variation of 
only.
So our final answer is option D that is "The mean score would decrease more than the median score."
Answer:
Max
Step-by-step explanation:
Lucas played 2 Rodeo Racing:8 Polar pinball = 1:4 (Divide by 2)
Max played 3 Rodeo Racing:9 Polar pinball = 1:3 (Divide by 3)
1:3 is greater than 1:4 so this proves that Max has played the greater ration of Rodeo Racing to Polar Pinball.

Answer:
C
Step-by-step explanation:
When we talk of rate of change, we talk of the slope of the line
If we had a line;
y = mx + b
m is the slope ( which is the rate of change)
To get the slope of the line, we select any two points on the line and apply the slope formula
m = y2-y1/x2-x1
let us take points (0,0) and (3,9)
m = 9-0/3-0 = 9/3 = 3
The slope here is 3
so from the option, we can see that the third option is the correct answer
