To find a point that satisfies both inequalities \( y > 4x - 2 \) and \( y \geq -13x + 2 \), we need to analyze the two equations that represent the boundaries of the inequalities.

  1. First Inequality: \( y > 4x - 2 \)

    • This line has a slope of 4 and a y-intercept of -2.
  2. Second Inequality: \( y \geq -13x + 2 \)

    • This line has a slope of -13 and a y-intercept of 2.

The solution to the system of inequalities will be the region that is above the line \( y = 4x - 2 \) and above (or on) the line \( y = -13x + 2 \).

To find potential points that lie in the solution area, we can substitute some values of \( x \) into both equations and check for their corresponding values of \( y \). Let's check a couple of points:

  1. For \( x = 0 \):

    • From \( y > 4(0) - 2 \): \( y > -2 \)
    • From \( y \geq -13(0) + 2 \): \( y \geq 2 \)
    • The point (0, 2) satisfies the second inequality but not the first, as \( 2 > -2 \).
  2. For \( x = 1 \):

    • From \( y > 4(1) - 2 \): \( y > 2 \)
    • From \( y \geq -13(1) + 2 \): \( y \geq -11 \)
    • The point (1, 3) satisfies both inequalities as \( 3 > 2 \) and \( 3 \geq -11 \).

Thus, the point (1, 3) is a solution for the simultaneous inequalities \( y > 4x - 2 \) and \( y \geq -13x + 2 \).

Final result:

(1, 3)
