Answer: 11.2 because I know trust me. I did a worksheet with this same question and got 11.2 and it was correct.
Answer:
Step-by-step explanation:
Hello!
The standard deviation (δ) is a measure of variability, this means, it shows how dispersed the data set is with respect to the mean. The population mean (μ) is a measurement of position. The three graphics have the same position μ=0 but their standard deviations change, this means, the form of their bells is different. The greater the value of the standard deviation, the more dispersed the data is you can see this graphically because the width of the bell will be greater.
Graph attached.

1) Since we have the slope, and one point we can find that linear equation using this point-slope formula. Plugging them we have:

2) Note that we had to add 1 to both sides, to keep the "y "on the left.
3) Therefore, y=-9x+10 is the answer.
C would equal -3 because you are going up 9 units
