Chapter 4: Q17. (page 244)

Write each equation in standard form.
$y - 5 = - 2 (x - 3)$

Short Answer

Expert verified

The equation in standard form is $y + 2 x = 11$ .

Step by step solution

Step 1. State the concept of the standard form of an equation.

A standard form of a linear equation is $A x + B y = C$ where $A \geq 0$ , $A$ and $B$ are not both zero, and $A, B$ and $C$ are integers with a greatest common factor of 1.

The slope-intercept form of a linear equation is $y = m x + b$ , where m is the slope and $b$ is the $y$ -intercept.

Step 2. Simplify the equation.

In order to simplify $y - 5 = - 2 (x - 3)$ , apply the distributive property on the right side.

$y - 5 = - 2 (x - 3) y - 5 = - 2 x - (- 2) \times 3 y - 5 = - 2 x + 6$

Step 3. Write the equation in standard form.

Further simplify the equation so as to rewrite the equation in the needed form of $A x + B y = C$ .

$y - 5 = - 2 x + 6 y - 5 + 5 = - 2 x + 6 + 5 Add5toeachside y + 2 x = - 2 x + 11 + 2 x Add 2 x toeachside y + 2 x = 11$

Thus, the equation in standard form is $y + 2 x = 11$ .
