The slope is 4/5, and the y-intercept is (0, –4).
Solución
The given function is f(x) = (4/5)x – 4.
Step 1. Find the Slope and y-intercept.
• The equation is already in slope-intercept form: f(x) = mx + b.
• The slope (m) is 4/5.
• The y-intercept (b) is –4, which corresponds to the point (0, –4).
Answer: Choice A. The slope is 4/5, and the y-intercept is (0, –4).
Step 2. Graphing the Function.
1. Plot the y-intercept: Begin at the point (0, –4) on the graph.
2. Use the slope: The slope 4/5 means you rise 4 units (up) and run 5 units (right). From (0, –4), move up 4 units to get to (0, 0) and then 5 units right to plot the point (5, 0).
3. Plot additional points if needed: You can also move in the opposite direction. From (0, –4), move down 4 units and 5 units left to find another point.
4. Draw a straight line through the points.
Your graph should display a line that crosses the y-axis at –4 and has a moderate upward tilt to the right.
Thus, the slope is 4/5 and the y-intercept is (0, –4).

The slope of the given linear function \( f(x) = \frac{4}{5} x - 4 \) is \( \frac{4}{5} \). The \( y \)-intercept, which is the value of \( f(x) \) when \( x=0 \), is -4. This means the line crosses the \( y \)-axis at the point (0, -4). To graph the function, start at the \( y \)-intercept (0, -4). From there, use the slope of \( \frac{4}{5} \) to rise 4 units and run 5 units to the right, which gives you an additional point at (5, 0). Connect these points with a straight line, and you've got your graph! Happy graphing! 🎉
