Range is from the lowest y value on the graph to the highest y value. There are different ways of writing range, and the way you write it depends on your teacher.
I will show you the ways I know. [-5,6]
-5 is less than or equal to 0 is less than or equal to 6
Ok y is your y value from any point on the graph m is your slope x is the x value of any point from the graph and b is your y intercept that is where the line cross in the y line that is the vertical line in the graph
