⭐️- Remember that slope formula is y=mx+b
1. Know that the m is (-3)
2. 4=(-3)(9)+b
3. 4=(-27)+b
4. b=31
5. y=(-3x)+31
6. y=3x-31*
*whenever it is finding a perpendicular, you switch the signs; when it is finding a parallel, you leave it alone
Answer:
6 is answer
Step-by-step explanation:
x+3=9
or, x=9-3(because we have to change sign)
therefore, x=6ans//
I want to say 5 but I'm not sure
