    • Linear Functions
      Algebra 1
    • Linear Functions
      • A linear function makes a line on a graph.
    • Linear Functions
      • A linear function makes a line on a graph.
      • A solution to a linear function is a point on the line.
    • Example 1
    • Graphing
      • The graph of a function is the set of ALL the points (x, y) that satisfy the equation.
    • Graphing
      • The graph of a function is the set of ALL the points (x, y) that satisfy the equation.
      • For a linear function, all these points together create a line.
    • Graphing
      • One way to graph a linear function is to create a table of values.

      • One way to graph a linear function is to create a table of values.
      Solve the equation for y.
    • Graphing
      • One way to graph a linear function is to create a table of values.
      Solve the equation for y.
      Choose a few x-values to plug in and find the corresponding y-values.
