Answer: -3 = k


Step-by-step explanation: y/x = k is the equation.

Okay so you plug in y into that equation and x also. You should have the equation -9/3 = k. All you do is solve! You should get -3=k. I hope this helped! :D

I need help finding the slope
grin007 [14]

answer:
-1

work:

y = mx+ b

so we can tell that the Y intercept is 1, so we can plug that in. ( + b is the y-intercept)

y = mx + 1

plug in some values to find the slope.
(-1, 2)
2 = -m + 1
- 1       - 1

1 = -1m 
/-1   /-1

-1 = m
the slope is -1.

i hope this helps! :D
