## anonymous one year ago y=-3x+6. Find the inverse and graph it

• This Question is Open
1. misty1212

can you solve $-3x+6=10$?

2. anonymous

-3x=4

3. misty1212

then?

4. anonymous

4/-3

5. misty1212

right steps were a) subtract 6 and then b) divide by $$-3$$ right?

6. misty1212

that is what the inverse does, subtract 6, divide by -3

7. misty1212

that makes the inverse $y=\frac{x-6}{-3}$

8. misty1212

or if you prefer $y=-\frac{1}{3}x+2$ either way

9. misty1212

you can always find the inverse by switching x and y and solving for y i.e. starting with $y=-3x+6$ switch to get $x=-3y+6$ solve for $$y$$$x=-3y+6\\ x-6=-3y\\ \frac{x-6}{-3}=y$

How do u graph that? By plugging in variables?
