Math Problem Statement

Use technology to find points and graph the line 2y + 6x = 6.

Solution

Let's solve the problem from the image. The equation given is:

2y+6x=62y + 6x = 6

Step 1: Simplify the equation

Solve for yy in terms of xx to rewrite the equation in slope-intercept form (y=mx+by = mx + b):

2y=6x+62y = -6x + 6

y=3x+3y = -3x + 3

Step 2: Find two points

To graph the line, select at least two values for xx, substitute them into the equation, and calculate the corresponding yy-values.

Example:

  1. Let x=0x = 0: y=3(0)+3=3y = -3(0) + 3 = 3 Point: (0,3)(0, 3)

  2. Let x=2x = 2: y=3(2)+3=6+3=3y = -3(2) + 3 = -6 + 3 = -3 Point: (2,3)(2, -3)

Step 3: Plot these points

  • Plot (0,3)(0, 3) on the graph.
  • Plot (2,3)(2, -3) on the graph.

Step 4: Draw the line

Connect the two points with a straight line, and extend it across the graph.

Would you like a graphical solution or further clarification? Here are some related questions for practice:


  1. What is the slope of the line y=3x+3y = -3x + 3, and how does it affect the graph?
  2. How would the line change if the equation was 2y+6x=122y + 6x = 12?
  3. How can you determine the yy-intercept and xx-intercept from the equation?
  4. How do you verify if a point (e.g., (1,6)(-1, 6)) lies on the line y=3x+3y = -3x + 3?
  5. What is the significance of graphing two points accurately?

Tip: Always choose simple xx-values (like 0, 1, or 2) for substitution when finding points to plot a straight line.
