Use this graph to answer these questions:

a. what is the y intercept

b. what is the slope.

c. what does the dashed line tell us?

d. what is the linear inequality equation for this graph.

answer each question individually.

The Visual Language of Dashed Lines. The dashed line is exquisitely rich with information. A line formed from a continuous series of dashes is diminished in strength when compared to a solid line, yet in terms of visual language, it is just as powerful.

            First, graph the "equals" line, then shade in the correct area. There are three steps: Rearrange the equation so "y" is on the left and everything else on the right. or below the line for a "less than" (y< or y≤).

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
