Question

functions and lines
solving a linear equation by graphing
here is an equation.
-9 = -3x
draw a graph to help solve the equation. then find the solution to the equation.
solution: x = 3

Explanation:

Step1: Analyze the equation

We have the equation \(-9 = -3x\). To solve for \(x\), we can divide both sides of the equation by \(-3\).

Step2: Solve for \(x\)

Dividing both sides by \(-3\), we get \(\frac{-9}{-3}=\frac{-3x}{-3}\). Simplifying both sides, \(\frac{-9}{-3} = 3\) and \(\frac{-3x}{-3}=x\), so \(x = 3\).

Answer:

\(x = 3\)
