• Use -6 as the y-intercept and find the next point by going down 1 in the y direction and over 2 in the x direction

• Use the equation to find the x and y intercepts and draw a line 

• Use the equation and plug in different numbers for x to find the corresponding y value.  Plot the ordered pairs on the line.

• Start at -1/2 on the y-axis and go down 6 in the y direction and over 1 in the x direction to find the next point. 

What is the equation of the line?

• Function 1 has a greater rate of change than function 2

• Function 2 has a greater rate of change than function 1

• Function 1 has a greater y-intercept than function 2

• Function 2 has a greater y-intercept than function 1
