To analyze the equation \(y = 4x - 6\), we can derive the following information:

  1. The line passes through the point (0, 6): This statement is false. To find the y-intercept, where \(x = 0\), substitute \(0\) into the equation: \[ y = 4(0) - 6 = -6. \] So the line passes through the point \((0, -6)\).

  2. The graph is a curved line: This statement is false. The given equation is linear, so the graph will be a straight line.

  3. The slope of the line is 4: This statement is true. In the equation \(y = mx + b\), \(m\) represents the slope. Here, the slope \(m\) is 4.

  4. The line passes through the origin: This statement is false. The line passes through the origin only if the y-intercept is 0. Since the y-intercept is \(-6\), the line does not pass through the origin.

  5. The y-intercept of the line is –6: This statement is true. From the calculation above, we see that when \(x = 0\), \(y\) is indeed \(-6\), therefore the y-intercept is \(-6\).

Summary of True Statements:

  • The slope of the line is 4.
  • The y-intercept of the line is –6.

Summary of False Statements:

  • The line passes through the point (0, 6).
  • The graph is a curved line.
  • The line passes through the origin.
