Can you help with this one? Given m = -1/5 and the point (1, 2), which of the following is the point-slope form of the equation?

y + 1 = -1/5(x + 1)

y + 2 = 1/5(x - 1)

y - 2 = -1/5(x - 1)

y + 2 = -1/5(x + 1)

Assume that adults have iq scores that are normally distributed with a mean of mu equals 100 and a standard deviation sigma equals 20. find the probability that a randomly selected adult has an iq between 80 and 120.assume that adults have iq scores that are normally distributed with a mean of mu equals 100 and a standard deviation sigma equals 20. find the probability that a randomly selected adult has an iq between 80 and 120.
