Answer:
You can display data in a histogram by labeling the x and y axis with your numbers provided. Then you put in the amount of numbers.
The answer is B. y = -1/5x +1/2.
EXPLANATION
First solve for the slope:
After finding the slope, look for the linear equation with the same value of m (parallel equation).
You need to substitute 9 with every x value in the equation.
So, 3(9)^2-7(9)+11
p(x)= 191
