What is the equation of this graphed line? coordinates are: (-4, -6) (2, 6) enter your answer in slope-intercept form in the box.

y=2x+2

Step-by-step explanation:

slope: 6-(-6)/2-(-4)=12/6=2

So, we know y=2x+b,

put one coordinate in the eqution(y=2x+b),

-6=2×(-4)+b

-6=-8+b

b=2

and y-intercept is (0,2)

so the equation is y=2x+b.

The answer is y=2x+2 :))

Step-by-step explanation:

answer: f = 32.2m

step-by-step explanation: that is the answer

irst, find the z score of a score of 80. this is given by the formula z = (x-u)/o, where x is the score, u is the mean, and o is the standard deviation. this gives

z = (80-78)/12 = 1/6 = .1667

now, find what percentile a z score of 1/6 correlates to in the normal distribution.

a z score of 1/6 = .1667 is equivalent to the 56.36th percentile of the distribution. so the probability a score is over this is 1-.5636 = .4364

the mean of a sample mean is equal to the original mean. however, the standard deviation of a sample mean is equal to the original standard deviation divided by the square root of n (sample size). so the new standard deviation is 12/sqrt(16) = 3.

the new z score is 80-78/3 = 2/3 = .667. this is equivalent to the 74.86th percentile. so the probability that the mean will be greater than this score is 1-.7486 = .2514.
