Word Problems

Example: Given the linear equation 3x - 5y = 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 2x + 3y = 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.
