Answer:
y=-x-0.833.....
Step-by-step explanation:
You solve for Y in the first two and then solve for x in the last two parts of the problem.
Answer:
i think it would be A
Step-by-step explanation:
6.0 because if it is 0-4, you round down and 5-9, round up
Answer: C) 5
--------------
x = independent variable, y = dependent variable
Assuming this is a linear function, each increase of x by 2 leads to y going up by 10. So 10/2 = 5 is the unit increase each time x bumps up by 1.
-------------------
An alternative is to use the slope formula to get
m = (y2 - y1)/(x2 - x1)
m = (25 - 15)/(4 - 2)
m = 10/2 <--- this expression shows up again
m = 5 <---- leading to the same answer as before
So we see that the slope formula is a more drawn out method to finding the answer.
