Answer:
The answer to your question is number 3.
Step-by-step explanation:
Data
A (4, 2)
B (0, 1)
Process
1.- Find the slope
m = (y2 - y1)/(x2 - x1)
- Substitution
m = (1 - 2) / (0 - 4)
- Simplification
m = -1/-4
= 1/4
2.- Find the equation of the line
y - y1 = m(x - x1)
- Substitution
y - 1 = 1/4(x - 0)
-Simplification
y - 1 = 1/4x
- Result
y = 1/4x + 1
