Chapter 4: Q. 45 (page 430)

In the following exercises, find three solutions to each linear equation.
$2 x + 4 y = 8$

Short Answer

Expert verified

The three solutions to given linear equation is $(0, 2), (4, 0), (1, \frac{3}{2})$

Step by step solution

Step 1. Given information

In the following exercises we have to find three solutions to each linear equation.
$2 x + 4 y = 8$

Step 2. We can substitute any value we want for x or any value for y.

Since the equation is in standard form, let’s pick first $x = 0, then y = 0$ , and then find a third point.

Step 3. Substitute the value into the equation.

$x = 0 y = 0 x = 1 2 x + 4 y = 8 2 x + 4 y = 8 2 x + 4 y = 8 2 \times 0 + 4 y = 8 2 x + 4 \times 0 = 8 2 \times 1 + 4 y = 8 4 y = 8 2 x = 8 2 + 4 y = 8 \frac{4}{4} y = \frac{8}{4} \frac{2}{2} x = \frac{8}{2} 2 + 4 y - 2 = 8 - 2 y = 2 x = 4 4 y = 6 \frac{4}{4} y = \frac{6}{4} y = \frac{3}{2}$

Step 4. Write the ordered pair.

$(0, 2) (4, 0) (1, \frac{3}{2})$
