C
Step-by-step explanation:
I solved in the picture
first look white, then blue
Hope this helps ^-^
The given equation is :
now, here
1. constant of proportionality for this direct variation is :
2. for the given table :
- x = 0 and y = 0
- x = 1 and y = -3
- x = 2 and y = -6
- x = 3 and y = -9
3. the given equation in slope intercept form will be :
where, slope (m) = -3 and y - intercept (b) = 0
4. graph is attached in attachment ~
