Solve for k, the constant of variation, in a direct variation problem, where x = 2 and y = 12. A. k= 1/24

B. k= 24

C. k= 6

D. k= 1/6

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

where are the graphs?

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
