Find the value of x pls .

What is the y intercept of f(x)=(1/2)^x?

How do you create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1?

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.
