7. Two students used point-slope form to find an equation that describes the line with a slope of -3 and goes through the point (-5, 2). Who is incorrect? Explain the error.
A
y - y = m(x - x)
y - 2 = -3(x - 5)
B. y - y = m(x-x.)
y-2--3[x -(-5)
y - 2 = -3(x+5)

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
