The label on a gallon of paint says that it will cover from 250 square feet to 450 square feet depending on the surface that is being painted. a painter has 12 gallons of paint on hand. the equation a 12c gives the area a (in square feet) that the 12 gallons of paint will cover if applied at a coverage rate c (in square feet per gallon).

The variable “c” is the independent variable so it is located on the x-axis. 
While the variable “A” is the dependent variable so it is located on the y-axis. 

Using the formula:

A = 12c

At c = 250, A = 3000. 
At c = 450, A = 5400. 

Now draw a point at coordinate (250, 3000), and another point at coordinate (450, 5400). Connect the 2 points with a line.

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.
