Answer 1

Answer:

-1/3x

Step-by-step explanation:

Known :

• x1 = -3
• x2 = 0
• y1 = 1
• y2 = 0

Asked :

• Correct line equation

Solution :

We can find the straight line equation using this formula,

$\frac{y-y1}{y2-y1} = \frac{x-x1}{x2-x1}$

Insert all we know inside the formula,

$\frac{y-1}{0-1} = \frac{x-(-3)}{0-(-3)}\\\frac{y-1}{-1} = \frac{x +3}{3}$

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
