Chapter 4: Q. 40 (page 430)

In the following exercises, find three solutions to each linear equation.
$x + y = - 1$

Short Answer

Expert verified

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

Step by step solution

Step 1. Given information

In the following exercises we have to find three solutions to each linear equation.
$x + y = - 1$

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.

$x = 0 y = 0 x = 1 x + y = - 1 x + y = - 1 x + y = - 1 0 + y = - 1 x + 0 = - 1 1 + y = - 1 y = - 1 x = - 1 1 + y - 1 = - 1 - 1 y = - 1 x = - 1 y = - 2$

Step 4. Write the ordered pair.

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