So -4 is where the line crosses the y axis (aka the y intercept). then to find other points, you can either count of the line by doing the slope (rise over run) in this scenario you would go up 8 and over 1 or you can plug in numbers for x and then can get ordered pairs for other points
Answer:
y= -5x-5
Step-by-step explanation:
because m=y2-y1/x2-x1 and then you plug in one of the point to find the y intercept or b and the answer you should get is -5 for be so it ends up being y= -5x-5
6 1/6, 5.5, 4 3/8, 4.3, 15/4
Answer:
Standard deviation =2.6
Step-by-step explanation:
Using the formula given
S = √((1/n-1)∑(x-x⁻)²)
n = 5
∑(x-x⁻)² = 34
Therefore;
s = √(1/5(34)
= √6.8
<u> = 2.6 </u>
The standard deviation will be 2.6
