Answer:
Step-by-step explanation:
first find the slope using the above points then use the slope formula to calculate the slope
substitute ⅔ for m and one of the above points into the y-intercept form of the equation for a line and solve for b
substitute the slope and the value for b into the equation to get the answer
Answer:
1) -95.
2) 15.
3) The conference center is on floor 5.
Step-by-step explanation:
1) Evaluating gives 
2) Substituting gives 
3) After going 4 floors down, we are on level -4. After going 9 floors up to the desired room, we are on level -4+9=5. So the conference center is on floor 5.
Slope of parallel line to this would be -1/3x
Answer:
12
Step-by-step explanation:
Because y=24 and x=2 you do the following:
144/24=6
Then, 6x2=12 because it is proportional
Or you could do 24/2=12 and 144/12=12
So if 54 is 100% then 200% is double therefore 200% of 54 is 108
