The flip-flop-alot company makes and sells flip-flops. they have one linear function that represents the cost of producing flip-flops and another linear function that models how much income they get from those flip-flops. describe the key features that would determine if these linear functions ever intercepted.

We can consider two linear functions:

and such that represents the the cost of producing flip-flops and   represents the income obtained on selling those flip flops.

Now when we plot the graph of these two linear functions then they will meet x and y-axis at some point so the point where the two linear functions intersect will be a break-even point and the point on the x-axis i.e. where y=0 is x-intercept; it represents that there is no income on either selling or purchasing the flip flop

the point where the line touches y-axis i.e. where x=0 is called y-intercept i.e. the cost of either purchasing or selling when no item is sold or purchased.
