Thank you for the opportunity to help you with your question!

- a line or linear function is always in the form of y =mx + c. In most cases when asked to graph such a function the value of m(slope) and C (x intercept) is usually known.

For the sake of this example our function will be y =2x +1

The first step is to determine the value of at least three points (x, y)

-to do this guess any three values of x and using the equation determine the corresponding values of Y.

My three points will be 0, 1 and 3

when x is 0

y = 2(0) +1 =1

when x is 1

y= 2(1) +1 = 3

when x is 3

y= 2(3) +1=7

x      0         1          3

y      1          3          7

my three points will thus be (0, 1) (1, 3) (3, 7)

On your Cartesian plane of x and y axis you can then plot the three points.

-Draw a line joining the three points.

-You will have graphed your linear equation

Please let me know if you need any clarification. I'm always happy to answer your questions.
