NEED ANSWERS ASAP!!! The graph represents revenue in dollars as a function of greeting cards sold.
Which equation represents the function shown on the graph?

Answer 1

Answer: $y=4x$

Step-by-step explanation:

From the given graph we can see that it is passing through origin (0,0) and (1,4).

The equation of a line passing through $(x_1,y_1)$ and $(x_2,y_2)$ is given by :-

$(y-y_1)=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Now, The equation of a line passing through (0,0) and (1,4) is given by :-

$(y-0)=\frac{4-0}{1-0}(x-0)\\\Rightarrow\ y=4x$
