To solve the system of linear equations by inspection:

  1. The equations given are:
    • \( y = 35x - 5 \)
    • \( y = -35x - 5 \)

To find if there are any intersections, we can set both equations equal to each other:

\[ 35x - 5 = -35x - 5 \]

  1. Adding \( 35x \) to both sides gives us:

\[ 35x + 35x = -5 + 5 \]

\[ 70x = 0 \]

  1. Dividing both sides by 70:

\[ x = 0 \]

  1. Now, substitute \( x = 0 \) back into either of the original equations to find the corresponding \( y \)-value. We can use the first equation:

\[ y = 35(0) - 5 = -5 \]

  1. Thus, the solution to the system of equations is \( (0, -5) \).

The options provided are:

  • (−5,0)
  • no solution
  • infinitely many solutions
  • (0,−5)

The correct response is (0,−5).
