Answer:
Slope = undefined
Step-by-step explanation:
Use the formula:
m = y2 - y1 / x2 - x1
Plug in the given information
m = 1 - 1 / 2 - - 6
Negative + Negative = Positive
m = 1 - 1 / 2 + 6
m = 0 / 8
m = 0/8
m = undefined
The equation y = -3|x|-1 describes the graph
Answer:
only Y
Step-by-step explanation:
all the others have for at least 1 value of x more than one different y values defined.
but a function must be clear about the association between an x unit value and the corresponding result.
many different input values can have the same functional result. but there can be only one defined result per input value. otherwise it is not a function.
you cannot say 1+1 = 2 or 3. it is either 2 or 3, but you need to define what. you can't leave it open.
Answer:
The answer to your question is This system of equations can not be solved. They do not cross.
Step-by-step explanation:
2x - 6y = 5 ----- (I)
x - 3y = -12 ----- (II)
I.- Solve equation II for x
x = 3y - 12 ------ (III)
2.- Substitute equation III on equation I
2(3y - 12) - 6y = 5
3.- Expand
6y - 24 - 6y = 5
6y - 6y = 5 + 24
0 = 29
This system of equations can not be solved.
