Answer:
D. y = -3x
Step-by-step explanation:
Firstly, find the coordinates:
(1, -3) and (2, -6)
Just from looking at these, you can tell that the y coordinate is multiplied by negative 3 but to find it using an equation, you can use the slope formula:
[tex]\frac{y2 - y1}{x2 - x1}[/tex]
Where x1 and y1 is the first set of coordinates and x2 and y2 is the second set. Simply plug the variables in:
[tex]\frac{-6 - -3}{2 - 1}[/tex]
[tex]\frac{-6 + 3}{1}[/tex]
[tex]\frac{-3}{1} = -3[/tex]
So the correct answer would be d.
Hope this helps!
