Chapter 4: Q. 4.39 (page 458)

Find the intercepts of $3 x + y = 12$ .

Short Answer

Expert verified

The x-intercept is (4, 0) and the y-intercept is (0, 12).

Step by step solution

Step 1. Given information.

The given equation is:

$3 x + y = 12$

Step 2. Determine the x-intercept.

Substitute $y = 0$ in the given equation to find the x-intercept.

$\begin{array}{rcl} 3 x + (0) & = & 12 \\ 3 x & = & 12 \\ x & = & \frac{12}{3} \\ x & = & 4 \end{array}$

The x-intercept is (4, 0).

Step 3. Determine the y-intercept.

Substitute $x = 0$ in the given equation to find the y-intercept.

$\begin{array}{rcl} 3 (0) + y & = & 12 \\ y & = & 12 \end{array}$

The y-intercept is (0, 12).

Step 4. Conclusion.

The x-intercept is (4, 0) and the y-intercept is (0, 12).
