Х -7, -3, -5, 3, 9, 16, 20 y=f(x) 3, 4, 5, 1, 8, 7, 11
The table shown at the right gives y as a function of x, that is, y = f(x). Use the table to answer parts a through d below.
a. Is - 7 an input or an output of this function?
b. Is f(-7) an input or an output of this function?
c. State the domain and range of this function.
d. Explain why this relationship describes y as a function of x.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
