Buatlah grafik dari fungsi :
a. Y = 25 + 5 X
b. Y = 100 – 5 X
c. Y = – 50 + 2 X

Here are the graphs of the following functions:

a. \( Y = 25 + 5X \) (blue line)  
b. \( Y = 100 - 5X \) (green line)  
c. \( Y = -50 + 2X \) (red line)

Each function is a straight line, with different slopes and intercepts, representing their respective linear relationships.

Would you like more details on these graphs or have any specific questions?

Here are 5 related questions to explore:
1. What is the slope of each function and how does it affect the graph?
2. How do the intercepts (the point where the line crosses the Y-axis) differ between the functions?
3. What happens if you modify the coefficient of \(X\) in these functions?
4. How would the graph change if the constant values were different?
5. Can these functions be used to model any real-life scenarios?

**Tip:** The slope of a linear function determines how steep the line is, and its sign tells you if the line is increasing or decreasing.

Learn how to graph the linear functions Y = 25 + 5X, Y = 100 - 5X, and Y = -50 + 2X. This tutorial covers key concepts such as the slope and y-intercept of linear equations, and provides detailed graphs of each function. Suitable for students in Grades 8-10.
