Suav's math teacher plots student grades on their weekly quizzes against the number of hours they say they study on the pair of coordinate axes and then
draws the line of best fit. Based on the line of best fit, what quiz score should
someone who studied 6 hours expect?

The random variable x represents the number of phone calls an author receives in a day, and it has a poisson distribution with a mean of 8.7 calls. what are the possible values of x

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

Which of the following is an equation of a line parallel to the equation y=4x+1?
