The \( y \)-intercept is \( (0,2) \).
Solución
1. **Find the \( y \)-intercept:**
Set \( x=0 \) in the equation:
\[
-0 + 4y = 8 \quad \Longrightarrow \quad 4y = 8
\]
Solve for \( y \):
\[
y = \frac{8}{4} = 2
\]
The \( y \)-intercept is \( (0,2) \).
2. **Find the \( x \)-intercept:**
Set \( y=0 \) in the equation:
\[
-x + 4(0) = 8 \quad \Longrightarrow \quad -x = 8
\]
Solve for \( x \):
\[
x = -8
\]
The \( x \)-intercept is \( (-8, 0) \).
3. **Graph the line:**
Plot the \( y \)-intercept \( (0,2) \) and the \( x \)-intercept \( (-8,0) \) on the coordinate plane. Draw a straight line through these two points.
Thus, the \( y \)-intercept is \( (0,2) \).

To find the \( y \)-intercept, set \( x = 0 \) in the equation \( -x + 4y = 8 \). This gives us \( 4y = 8 \), so \( y = 2 \). Therefore, the \( y \)-intercept is \( (0, 2) \). Now, for the \( x \)-intercept, set \( y = 0 \). The equation becomes \( -x + 4(0) = 8 \), leading to \( -x = 8 \), thus \( x = -8 \). So, the \( x \)-intercept is \( (-8, 0) \). Plot the points \( (0, 2) \) and \( (-8, 0) \) on a graph and draw a line through them to graph the line!
