Solve the problems.
1 martin has an 18-cup container of flour that he uses for
muffins only. he uses 3 cups of the flour for every batch
of muffins he makes. write an equation to show how
much flour is left in the container after x batches of
muffins. then graph the function.
show your work.

Step-by-step explanation:

Let the amount of flour left be .

Initial amount of flour = 18 cups

Cups used for 1 batch of muffins = 3

∴ Cups used for batches =

Amount left in the container is given as:

Therefore, the equation to show how  much flour is left in the container after x batches of  muffins is .

The graph of it is shown below.

Find the x and y intercepts and then join the line.

At x intercept,

So, x intercept is

At y intercept, ,

So, y intercept is

Join these two points to plot the graph.
