Chapter 4: Q. 43 (page 430)

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

Short Answer

Expert verified

The three solutions to given linear equation is $(0, - 8), (2, 0), (1, - 4)$

Step by step solution

Step 1. Given information

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

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.

$x = 0 y = 0 x = 1 4 x - y = 8 4 x - y = 8 4 x - y = 8 4 \times 0 - y = 8 4 x - 0 = 8 4 \times 1 - y = 8 - y = 8 4 x = 8 4 - y = 8 - y \times (- 1) = 8 \times (- 1) \frac{4}{4} x = \frac{8}{4} 4 - y - 4 = 8 - 4 y = - 8 x = 2 - y = 4 y = - 8 x = 2 - y \times (- 1) = 4 \times (- 1) y = - 8 x = 2 y = - 4$

Step 4. Write the ordered pair.

$(0, - 8) (2, 0) (1, - 4)$
