We can write:
Spending $12 decreases the money in your bank account. "at least 51" means you have 51 or more, so we use the greater than or equal to sign.
Is it asking about the slope of this vertical line? if so, then the answer is "undefined". The rise is any number you want, let's say 1, and the run is 0
slope = rise/run = 1/0 = undefined
you cannot divide by zero
I don’t know if this will help
A lot but To convert temperatures in degrees Celsius to Fahrenheit, multiply by 1.8 (or 9/5) and add 32.
(-89.2°C × 9/5) + 32 = -128.6°F
This would equal 3/2 or 1.5.
Hope this helps!
