change in y/change in x
y2-y1/x2-x1
-1--5/0-2
-1+5/-2
4/-2
-2
slope is -2
now take one ordered pair and plug it into the equation (for this example i will use the SECOND ordered pair
y = -2x +b
-1 = -2(0)+b
-1 = b
the equation is
<h2>
y = -2x - 1</h2>
Answer:
If X repeats and y does not it is not an example of a function. But if the y repeats and has two different x values that can be known as a function.
For an example ( 1 , 3) and (1, 4) thats not an example of a function because the x value is repeating but if its ( 1, 4) and (2,4) a thats
a function because no x value is repeating the x value is known as an independent value. Does that make sense?
"This relation is definitely a function because every x-value is unique and is associated with only one value of y. So for a quick summary, if you see any duplicates or repetitions in the x-values, the relation is not a function."
Uhhhhh me speak no Spanish sorry
The answer is “C”. None of the above
Answer:
x+4
Step-by-step explanation:
The ratio of area to width is ...
area / width = (x^2 +3x -4)/(x -1) = ((x -1)(x +4))/(x -1) = x +4

Effectively, you are being asked to do polynomial division. This can be accomplished several ways. The method shown above is by factoring the numerator and cancelling the common factor from numerator and denominator.
You can also do this by synthetic division or long divison. The attachment shows synthetic division giving the same answer. (Numerous resources, including Wikipedia and You.Tube, are able to explain synthetic division in detail.)
