**Word Problems**

**Example**: Given the linear equation 3

*x*- 5

*y*= 30: Express it in slope-intercept form and graph it and label the

*x*- and

*y*-intercepts on the graph.

**Example**: Find the

*x*- and

*y*-intercepts and use them to graph 2

*x*+ 3

*y*= 6.

**Example**: Graph the linear function

*f*(

*x*) = -2/3

*x*+ 8 and calculate

*f*(6).

**Example**: Are the two lines parallel, perpendicular, or neither?

Determine and compare the slopes of each line in the given system.

**Example**: Graph the following two lines on the same set of axes and indicate where they intersect.

**Example**: Find the equation of the line that is passing through (8, -2) and parallel to the line passing through (-3, -2) and (5, 1).

**Example**: Find the equation of the line that is passing through (2, -1) and perpendicular to

*y*= 3/5

*x*+ 2.

**Example**: Find the equation of the line passing through (3, 5) and (3, -4). Graph the line and label any intercepts.
