To determine if the two lines intersect, we can calculate their slopes and check their relationship.

  1. Line through (3, 7) and (-2, -5):

    • The slope \( m_1 \) is calculated using the formula: \[ m_1 = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-5 - 7}{-2 - 3} = \frac{-12}{-5} = \frac{12}{5} \]
  2. Line through (4, 8) and (10, -2):

    • The slope \( m_2 \) is calculated similarly: \[ m_2 = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-2 - 8}{10 - 4} = \frac{-10}{6} = -\frac{5}{3} \]
  3. Comparison of slopes:

    • The slopes \( m_1 = \frac{12}{5} \) and \( m_2 = -\frac{5}{3} \) are neither equal nor negative reciprocals of each other (which would mean they are perpendicular).

Since the slopes are different, the lines are not parallel.

Thus, the correct response is: Yes…these lines are not parallel.
