Put this into slope intercept form.
y = 6 - x becomes y = -x + 6
"m" is the coefficient on x: -1
"c" is the number without the x: 6
a is given to us so just plug a into the first equation:
b-3 - 3b =9
Add 3 to both sides:
b-3b=12
Combine like terms:
-2b=12
Divide by -2 to get b by itself:
b=-6
The only answer with b as -6 is the first one, (-9,-6)
I think 90 im not sure tho i searched it up
