    Cards (7)

    • Linear Equation in Two Variables
      An equation that can be written in the standard form Ax + By = C, where A, B, and C are real numbers, and A and B are both nonzero
    • Not a Linear Equation in Two Variables: 3x^2 - y = 9
    • Determine whether or not each equation is a linear equation in two variables

      1. 2x^2 - 3x + 2 = 0
      2. 3x - 4y = 8 - 4x
      3. x - 5 = 3x - 3
      4. x - 3x = 2
      5. y + 7x = 3
    • Solution of Linear Equation
      Ordered pairs that make the equation true
    • Determine if (-1, 3) is a solution of x + 3y = 8
      • (-1) + 3(3) = 8
      • -1 + 9 = 8
      • 8 = 8
    • Solve for y and complete the table of values. Plot the graph of the equation y = 4x - 1
      1. y = 4x - 1
      2. x y
      3. 0 -1
      4. -1 -5
      5. 1 3
      6. 2 7
    • Complete the table and plot the line y = 3x + 2
      1. x y
      2. -2
