To estimate the solution to the system of linear equations given by the equations \( y = 5x + 10 \) and \( y = -2x + 3 \), we can find the intersection point by setting the two equations equal to each other:

\[ 5x + 10 = -2x + 3 \]

Now, let's solve for \( x \):

  1. Add \( 2x \) to both sides: \[ 5x + 2x + 10 = 3 \] This simplifies to: \[ 7x + 10 = 3 \]

  2. Subtract \( 10 \) from both sides: \[ 7x = 3 - 10 \] This simplifies to: \[ 7x = -7 \]

  3. Divide both sides by \( 7 \): \[ x = -1 \]

Now, substitute \( x = -1 \) back into one of the original equations to find \( y \). We'll use \( y = -2x + 3 \):

\[ y = -2(-1) + 3 \] \[ y = 2 + 3 \] \[ y = 5 \]

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

Based on the given choices:

  • (5, -1)
  • (1, 5)
  • (-1, -5)
  • (-1, 5)

The correct response is \((-1, 5)\).
