8x-9y=11
First you move the 8x because you have to leave the 9y alone
8x-9y=11
-8x -8x
-9y=11-8x
Now you have to move the -9, so the inverse of multiplying is dividing so you divide -9.
-9y/-9= 11/-9 -8x/-9
since you can't have negative as a denominator it would be:
y= -11/9+8x/9

9 = 3^2
Since 3 squared equals 9, that is how 9 as a power of the base 3 should be written.
Answer:
The slope is zero.
Step-by-step explanation:
If it is rational, it has a terminating decimal or a repeated decimal number (ex. 56, or 1.25, or 3.666...)
If it is irrational, it is an ongoing number with no pattern (ex. 3.14159265... Which is pi)
4(73)+3
273+3
276
Because you have to subsititue 73 for x. So you have to multiply 73 by 4 then what you get out of that you have to add it by 3.
