If x is a number that is 7 more than y, how do you express x as a function of y?
a. x = f(y) = 7 + x
b. x = f(y) = 7 + y
c. y = f(x) = 7x
d. y = f(x) = y – 7
e. y = f(x) = 7 + y

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.
