To find the x-intercept of the line given by the equation \( 8x - 4y = -24 \), we set \( y = 0 \) and solve for \( x \).
Substituting \( y = 0 \) into the equation:
\[
8x - 4(0) = -24
\]
This simplifies to:
\[
8x = -24
\]
Now, divide both sides by 8:
\[
x = \frac{-24}{8} = -3
\]
Therefore, the x-intercept is:
**B. -3**.
Substituting \( y = 0 \) into the equation:
\[
8x - 4(0) = -24
\]
This simplifies to:
\[
8x = -24
\]
Now, divide both sides by 8:
\[
x = \frac{-24}{8} = -3
\]
Therefore, the x-intercept is:
**B. -3**.
