To determine your final grade, why might you prefer your teacher use the mean of your test scores to determine your final grade instead of the median?

When determing your grade using mean, it will be more accurate to give your final grade rather then median. If you had one F for example, if that ends up being in the middle it could be your final grade

i am not sure :

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
