Hey! :)
So when we write something in slope intercept form, all we're doing is solving for y. So let's do that with this equation!
-2x + y = 9
add 2x to both sides
y = 2x + 9
So C is your answer.
Please let me know if you need anything further explained!
1/3 (8-x)
Hope that helps, good luck
1. y= -2x +3
2. y = -4/5x - 15
3. y = -1/3x - 4
4. y = - x + 8
5. y = -4x
6. y = -3/2x -7
