Sasha noticed that the graph of the sales of yearbooks represented a proportional relationship. how could she have calculated the constant of proportionality by looking at the graph?
she could divide any y-value by its corresponding x-value.
she could divide any x-value by its corresponding y-value.
she could add any y-value to its corresponding x-value.
she could subtract any x-value from its corresponding y-value.

Find the average rate of change for f(x) = x2 − 3x − 10 from x = −5 to x = 10.

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.
