The correct Answer is:
To find the value of \( m \) for the line \( y = mx + 8 \) that contains the point \((-4, 4)\), we can follow these steps: ### Step 1: Substitute the point into the line equation We know that the point \((-4, 4)\) lies on the line. Therefore, we can substitute \( x = -4 \) and \( y = 4 \) into the equation \( y = mx + 8 \). \[ 4 = m(-4) + 8 \] ### Step 2: Simplify the equation Now, we simplify the equation: \[ 4 = -4m + 8 \] ### Step 3: Isolate the term with \( m \) Next, we want to isolate the term with \( m \). We can do this by moving \( 8 \) to the left side of the equation: \[ 4 - 8 = -4m \] This simplifies to: \[ -4 = -4m \] ### Step 4: Solve for \( m \) Now, we can solve for \( m \) by dividing both sides of the equation by \(-4\): \[ m = \frac{-4}{-4} = 1 \] ### Conclusion Thus, the value of \( m \) is \( 1 \). ---
