Question

when y is 9.2, what value of x makes the equation true?
y = -2x - 4

Explanation:

Step1: Substitute y with 9.2

We know the equation is \( y = -2x - 4 \), and \( y = 9.2 \). So we substitute \( y \) in the equation:
\( 9.2 = -2x - 4 \)

Step2: Solve for x

First, add 4 to both sides of the equation:
\( 9.2 + 4 = -2x - 4 + 4 \)
\( 13.2 = -2x \)
Then, divide both sides by -2:
\( x=\frac{13.2}{-2}=-6.6 \)

Answer:

-6.6
