Students graph a linear equation and compute
the x- and y-intercepts, and they are also able
to sketch the region defined by a linear inequality.

Previously Published Data 

1.) Students will work in groups of four to solve the following problems: 

  • A candle is 20 cm tall. After burning for 0.5 hour, the candle is 19 cm tall. Make a table of values showing the height of the candle after 5 different times. Plot those points on a set of axes. Write an equation that models the height of the candle c in terms of the number of hours h that it burns. 
  • Adrienne has a $100 that she wants to spend on new CDs and videos. Assume that a CD costs $10 and a video costs $12. Write this situation as an inequality. Try some pairs of numbers for the variables, testing whether or not each pair satisfies the inequality. Using one shared set of coordinate axes per group, each member should mark points based on the following: if the point satisfies the inequality, it is marked one color; if the point does not satisfy the inequality, it is marked in another color.

    1.) Students will solve the following: Membership in a gym cost $130 plus $30 per month. Write an equation that models the cost of membership c in terms of the number of months you belong. Graph your solution. 


    2.) Students will graph 5x + 2y less than or equal to 30
