To solve the equation \( 9x - 6 = -8 \) graphically, you can rearrange it into a standard form that can easily be graphed. Here’s how you can do it:
- Rearrange the equation: First, isolate \( x \) on one side of the equation.
\[ 9x - 6 = -8 \implies 9x = -8 + 6 \implies 9x = -2 \implies x = -\frac{2}{9} \]
-
Graph the functions: To solve it graphically, you can graph two functions:
- \( y = 9x - 6 \)
- \( y = -8 \)
-
Plot the graphs:
- For \( y = 9x - 6 \), this is a straight line with a slope of \( 9 \) and a y-intercept of \( -6 \).
- For \( y = -8 \), this is a horizontal line where the y-value is always \(-8\).
-
Find the intersection: The solution to the equation \( 9x - 6 = -8 \) corresponds to the \( x \)-coordinate of the intersection point of these two lines.
By plotting these two functions, the \( x \)-coordinate of their intersection will give you the value of \( x \) that satisfies the original equation. In this case, you would find \( x = -\frac{2}{9} \).
