Math Problem Statement

What are the solutions to the system of equations composed of the line y = -2x + 4 and the equation represented in the graph?

Solution

The problem asks for the solutions to the system of equations involving the line y=2x+4y = -2x + 4 and the equation represented by the graph, which appears to be a quadratic function (parabola).

To solve this system graphically, we need to identify the points where the line intersects the parabola. The given options are:

  1. (3,2)(3, -2) and (4,0)(4, 0)
  2. (2,2)(2, -2) and (1,0)(1, 0)

Steps:

  1. Line Equation: The line is y=2x+4y = -2x + 4, which has a slope of 2-2 and a y-intercept at (0,4)(0, 4).
  2. Graph Analysis: The parabola intersects the x-axis at (4,0)(4, 0) and (1,0)(1, 0), and has a vertex at approximately (2.5,2)(2.5, -2).
  3. Intersection Points:
    • Looking at the graph, the points where the line seems to intersect the parabola are around (2,2)(2, -2) and (1,0)(1, 0).

Thus, the solution to the system of equations is likely the points (2,2)(2, -2) and (1,0)(1, 0), making the correct answer:

(2,2) and (1,0)\boxed{(2, -2) \text{ and } (1, 0)}
