DMA 050 Graphs/Equations of Lines (1 Credit Hour)


Class Hours: .75
Lab Hours: .50
Clinical/Work Experience Hours: 0
Prerequisites: DMA 010 , DMA 020 , DMA 030 , DMA 040 , or MAT 060 , or appropriate placement test scores.
Corequisites: None
This course provides a conceptual study of problems involving graphic and algebraic representations of lines. Topics include slope, equations of lines, interpretation of basic graphs, and linear modeling. Upon completion, students should be able to solve contextual application problems and represent real-world situations as linear equations in two variables.

Competencies:

  • Read and interpret basic graphs to solve problems
  • Apply the concept of slope as a rate of change in real-world situations
  • Write and graph linear equations in two variables to model real-world situations
  • Represent real-world situations as linear equations in two variables in tabular form, graphically, and algebraically

Student Learning Outcomes:

5.1 Analyze and interpret basic graphs to solve problems
5.2 Represent real world situations in tabular, graphical, and algebraic equation form using two variables
5.3 Generate a table of values given an equation in two variables and plot in Cartesian plane to graph a line
5.4 Demonstrate an understanding of the concept of slope as a rate of change in real world situations using the slope formula
5.5 Find and interpret the x- and y-intercepts of linear models in real world situations
5.6 Graph linear equations using a variety of strategies
5.7 Given a contextual application, write a linear equation and use the equation to make predictions
5.8 Demonstrate a conceptual understanding of horizontal and vertical lines in terms of slope and graphically
5.9 Demonstrate a conceptual understanding of the concept of an algebraic function
