Answer
The \( x \)-intercept is \( (2, 0) \).
Solution
To find the intercepts of the equation \( 3x + 4y = 6 \), we will determine both the \( x \)-intercept and the \( y \)-intercept.
### (a) Finding the intercepts
**1. Finding the \( x \)-intercept:**
The \( x \)-intercept occurs when \( y = 0 \). We can find it by substituting \( y = 0 \) into the equation:
\[
3x + 4(0) = 6
\]
\[
3x = 6
\]
\[
x = 2
\]
So, the \( x \)-intercept is \( (2, 0) \).
**2. Finding the \( y \)-intercept:**
The \( y \)-intercept occurs when \( x = 0 \). We can find it by substituting \( x = 0 \) into the equation:
\[
3(0) + 4y = 6
\]
\[
4y = 6
\]
\[
y = \frac{6}{4} = \frac{3}{2}
\]
So, the \( y \)-intercept is \( (0, \frac{3}{2}) \).
### Summary of intercepts:
- The \( x \)-intercept is \( (2, 0) \).
- The \( y \)-intercept is \( (0, \frac{3}{2}) \).
### (b) Graphing the equation
To graph the equation \( 3x + 4y = 6 \), we can plot the intercepts we found:
1. Plot the \( x \)-intercept \( (2, 0) \).
2. Plot the \( y \)-intercept \( (0, \frac{3}{2}) \).
Next, draw a straight line through these two points. The line represents all the solutions to the equation \( 3x + 4y = 6 \).
### Final Answers:
A. The \( x \)-intercept is \( (2, 0) \).

Extra Insights
To find the \( x \)-intercept of the equation \( 3x + 4y = 6 \), set \( y = 0 \). This simplifies the equation to \( 3x = 6 \), leading to \( x = 2 \). So, the \( x \)-intercept is at the point \( (2, 0) \). For the \( y \)-intercept, set \( x = 0 \) in the original equation. This gives \( 4y = 6 \) or \( y = \frac{3}{2} \). Therefore, the \( y \)-intercept is at the point \( (0, \frac{3}{2}) \). Plotting these two points on a coordinate graph will allow you to draw the line, which will slope downwards from the \( y \)-intercept to the \( x \)-intercept!
