Graph the following and then answer the questions given below: 2x-3y Greater than or equal to 6

a) Describe the method you used to graph this inequality.

b) Where does the line cross the x-axis(write as an ordered pair)?

c) Where does the line cross the y-axis(write as an ordered pair)?

d) Is the origin on the right side or the left side of the line?

e) Is the line solid or dashed?

f) Which side of the line is shaded (left side or right side)?

g) How did you determine which side of the line to shade?

The third method for graphing the solution set is to use the slope and y-intercept. Answer the following:

a) Find the slope and the y-intercept of the line formed by the following equation. Provide an in-between step: 9x - 3y = 15.

b) Explain how you would use the slope and y-intercept to graph the line represented by this equation.

Use the intercept method to graph this equation: -4x + 2y = 8
a) What is the x-intercept(write as an ordered pair)?

b) What is the y-intercept(write as an ordered pair)?

c) Is the origin on the right or left side of the line?

Another method for graphing a line is by finding the x and y-intercepts. Explain how you find these intercepts.

Create a list (table) of three solutions for this equation: 3x + 2y = -18. Provide work to support the solutions and write the solutions as ordered pairs.
