In the following exercises, graph by plotting points.
Write the inequality shown by the graph with the boundary line y = 3x − 4.

Write the inequality shown by the graph with the boundary line y=2x - 4.

find an equation of a line parallel to the line y= -2x-3 and contains the point (-1,3). Write the equation in slope–intercept form.
An easy way to determine the slope of a roof is to set one end of a 12 inch level on the roof surface and hold it level. Then take a tape measure or ruler and measure from the other end of the level down to the roof surface. This will give you the slope of the roof. Builders, sometimes, refer to this as pitch and state it as an "12 pitch" meaning , where is the measurement from the roof to the level—the rise. It is also sometimes stated as an " -in-12 pitch".
a) What is the slope of the roof in this picture?
b) What is the pitch in construction terms?
