Math Problem Statement

Find the x-intercept and the y-intercept of the graph of the equation 2x + 3y = 6.

Solution

To find the x-intercept and y-intercept for the given equation 2x+3y=62x + 3y = 6:

1. X-intercept

The x-intercept occurs when y=0y = 0. Substitute y=0y = 0 into the equation:

2x+3(0)=62x + 3(0) = 6

2x=6    x=32x = 6 \implies x = 3

So, the x-intercept is 33, which is already provided.


2. Y-intercept

The y-intercept occurs when x=0x = 0. Substitute x=0x = 0 into the equation:

2(0)+3y=62(0) + 3y = 6

3y=6    y=23y = 6 \implies y = 2

So, the y-intercept is 22.

Final Answer:

  • X-intercept: 33
  • Y-intercept: 22

Let me know if you'd like further clarification on the steps! Here are some related questions to practice:

  1. What are the intercepts of 4x+5y=204x + 5y = 20?
  2. How do you graph a line given its intercepts?
  3. Can you derive the slope from the intercepts?
  4. What happens to the intercepts if you multiply the equation by a constant?
  5. How do intercepts relate to the slope-intercept form of an equation?

Tip: When finding intercepts, always substitute y=0y = 0 for the x-intercept and x=0x = 0 for the y-intercept.
