Answer:
-1/3x
Step-by-step explanation:
Known :
- x1 = -3
- x2 = 0
- y1 = 1
- y2 = 0

Solution :
We can find the straight line equation using this formula,
[tex]\frac{y-y1}{y2-y1} = \frac{x-x1}{x2-x1}[/tex]
Insert all we know inside the formula,
[tex]\frac{y-1}{0-1} = \frac{x-(-3)}{0-(-3)}\\\frac{y-1}{-1} = \frac{x +3}{3}\\[/tex]
Use cross multiplication,
3(y - 1) = -1(x + 3)\
3y - 3 = -x - 3
3y = -x - 3 + 3
3y = -x
y = -1/3x
Conclusion :
The correct equation is y = -1/3x
