To find the x-intercept of the line represented by the equation 2x + 12y = 18, we need to determine the point at which the line crosses the x-axis. The x-intercept occurs when the value of y is equal to zero.
Here are the steps to find the x-intercept:
- Start with the equation: 2x + 12y = 18.
- Substitute y = 0 into the equation since we are looking for the x-intercept.
- The equation becomes: 2x + 12(0) = 18.
- This simplifies to: 2x = 18.
- Now, solve for x:
- Divide both sides by 2:
x = 18 / 2. - This gives us: x = 9.
- Divide both sides by 2:
Therefore, the x-intercept of the line represented by the equation 2x + 12y = 18 is (9, 0).
