A: Since there is no cluster formed in the scatterplot, the two variables
are not related. Therefore, based on the data shown in the scatterplot,
the number of fish in a lake is not dependent on the size of the lake.
Answer:
-2
Step-by-step explanation:
Answer: ![y=2.5x+2.5](https://tex.z-dn.net/?f=y%3D2.5x%2B2.5)
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Where "m" is the slope and "b" is the y-intercept.
Since we know that the line passes through the point (2,7.5) and (-1,0), we can find the slope with this formula:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Substituting values, we get:
![m=\frac{0-7.5}{-1-2}\\\\m=2.5](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B0-7.5%7D%7B-1-2%7D%5C%5C%5C%5Cm%3D2.5)
In order to find the y-intercept, we can substitute the slope and the point (-1,0) into
and then solve fo "b":
![0=(2.5)(-1)+b\\\\0=-2.5+b\\\\b=2.5](https://tex.z-dn.net/?f=0%3D%282.5%29%28-1%29%2Bb%5C%5C%5C%5C0%3D-2.5%2Bb%5C%5C%5C%5Cb%3D2.5)
Then, the equation of this line in Slope-Intercept form is:
![y=2.5x+2.5](https://tex.z-dn.net/?f=y%3D2.5x%2B2.5)
Answer:
45 i believe
Step-by-step explanation:
The lowest value of the range of the function would be -2, as this is the lowest the y value goes
