To determine which equations are in y = mx + b form, we need to check if each equation can be expressed in that format, where m is the slope and b is the y-intercept.

  1. y = 5x - 4: This is already in y = mx + b form (m = 5, b = -4).

  2. y = -2x + 3: This is also in y = mx + b form (m = -2, b = 3).

  3. y = 3x + 1: This is in y = mx + b form (m = 3, b = 1).

  4. 2y = 6x + 2: To convert to y = mx + b, divide by 2:
    y = 3x + 1, which is in y = mx + b form.

  5. y - 5x = 2: Rearranging gives y = 5x + 2, which is in y = mx + b form.

  6. y - 4x + 1 = 0: Rearranging gives y = 4x - 1, which is in y = mx + b form.

Summary: All of the given equations can be expressed in y = mx + b form. Thus, the answer is that all options (1, 2, 3, 4, 5, and 6) are in y = mx + b form.
