Math Problem Statement

Escribir un sistema de ecuaciones lineales para el siguiente gráfico.

Solution

To solve this task, we need to identify the equations of the two lines in the graph, as the problem requires creating a system of linear equations from the graph.

Steps:

  1. Identify the slope and y-intercept for each line.

    • Line 1: Find two points on the line and calculate the slope mm using m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1}. Then, use the slope-intercept form y=mx+by = mx + b to find bb.
    • Line 2: Repeat the process.
  2. Confirm the intersection point.

    • The system of equations should reflect the given lines and their intersection point.

Let me analyze the image and extract the points to calculate the equations. PIL import Image import pytesseract

Load the uploaded image

image_path = "/mnt/data/1732889656353n3kf4o3f.jpg" image = Image.open(image_path)

Use OCR to extract any visible text (not needed for calculations, but just in case)

extracted_text = pytesseract.image_to_string(image)

extracted_textThe OCR did not extract meaningful text. However, from the image, the points and slopes will be determined visually. Based on the graph:

  1. Line 1:

    • Points: For this line, it appears to pass through (8,8)(-8, 8) and (4,4)(4, -4).
    • Slope: m=484(8)=1212=1m = \frac{-4 - 8}{4 - (-8)} = \frac{-12}{12} = -1.
    • Equation: y=x+by = -x + b. Using one point (8,8)(-8, 8): 8=(8)+b    8=8+b    b=08 = -(-8) + b \implies 8 = 8 + b \implies b = 0 So, the equation is y=xy = -x.
  2. Line 2:

    • Points: This line passes through (8,4)(-8, -4) and (8,4)(8, 4).
    • Slope: m=4(4)8(8)=816=12m = \frac{4 - (-4)}{8 - (-8)} = \frac{8}{16} = \frac{1}{2}.
    • Equation: y=12x+by = \frac{1}{2}x + b. Using one point (8,4)(-8, -4): 4=12(8)+b    4=4+b    b=0-4 = \frac{1}{2}(-8) + b \implies -4 = -4 + b \implies b = 0 So, the equation is y=12xy = \frac{1}{2}x.

System of Equations:

y = -x \\ y = \frac{1}{2}x \end{cases}$$ Would you like me to verify or explain any part in detail? Here are 5 questions to expand your understanding: 1. How is the slope formula derived? 2. How do we confirm if a point lies on a line? 3. What does the intersection point of the two lines represent? 4. How would the equations change if one line was vertical? 5. Can this method apply to nonlinear systems? **Tip:** Always double-check points from graphs to avoid minor errors.
