a) The opposite table represents a linear relation:
| \( X \) | 1 | 2 | 3 |
|---|---|---|---|
| \( y = f(X) \) | 1 | 3 | a |
1. Find the equation of the straight line.
2. Find the length of the intercepted part from y-axis.
3. Find the value of a
2. Find the length of the intercepted part from y-axis.
3. Find the value of a
Solution:
1. The equation of the straight line is \( y = 2x - 1 \)
2. One unit of the negative part of y-axis
3. \( a = 2 \times 3 - 1 = 5 \)
