Are the graphs of the lines in the pair parallel? Explain.

y =3/7 x + 11
–3x + 7y = 13

1 answer

To determine if the two lines are parallel, we need to compare their slopes. Two lines are parallel if they have the same slope.

  1. Find the slope of the first line: The first line is given in slope-intercept form \( y = mx + b \): \[ y = \frac{3}{7}x + 11 \] Here, the slope \( m_1 \) is \( \frac{3}{7} \).

  2. Convert the second line to slope-intercept form: The second line is given as: \[ -3x + 7y = 13 \] We can rearrange this to solve for \( y \): \[ 7y = 3x + 13 \] \[ y = \frac{3}{7}x + \frac{13}{7} \] Here, the slope \( m_2 \) is also \( \frac{3}{7} \).

  3. Compare the slopes: Since both lines have the same slope: \[ m_1 = \frac{3}{7} \quad \text{and} \quad m_2 = \frac{3}{7} \]

  4. Conclusion: Yes, the graphs of the lines in the pair are parallel because they have the same slope of \( \frac{3}{7} \).
