Which two points lie on a line with an undefined slope?

Mathematics

Slope formula is
m = (y2 - y1)/(x2 - x1)

A. m = (5 - 0)/(-2 + 2)
m = (5)/(0)
m = error

B. m = (-2 - 0)/(0 + 2)
m = (-2)/(2)
m = -1

C. m = (2 - 0)/(2 - 0)
m = (2)/(2)
m = 1

D. m = (0 - 0)/(2 - 3)
m = (0)/(-1)
m = 0

the undefined slope would be the one that came out as error, so A

Answer:

Option A.  (-2,0) and (-2,5)

Step-by-step explanation:

we know that

A vertical line has an undefined slope

The lines parallel to the y-axis are vertical lines

The points that lie on a vertical line has the same x-coordinate

In this problem

the points (-2,0) and (-2,5) has the same x-coordinate

therefore

The points lie on a line with  an undefined slope (vertical line)

A spinner is divided into 8 section of equal size. The sections are numbered 1 through 8. Use this information to determine the
olga_2 [115]

1) 1/8

2) 1/2

Step-by-step explanation:

1)

First of all, we notice that the spinner is divided into 8 sections of equal size.

So the number of sections is

n = 8

Secondly, we note that each section has the same size: this means that the probability of the spinner landing on each section is the same.

The probabilty of a certain event A to occur is given by

p(A)=\frac{a}{n}

where

a is the number of successfull outcomes (in which A occurs)

n is the total number of possible outcomes

Here we want to find

p(7) = probability that the spinner lands on section 7

Here we have:

a=1 (only 1 outcome is successfull: the one in which the spinner lands on section 7)

n=8

Therefore, the probability is

p(7)=\frac{1}{8}

2)

Here we want to find the probability that the spinner lands on an even numbered section.

As before, the total number of possible outcomes his:

n=8

which corresponds to: 1, 2, 3, 4, 5, 6, 7, 8

The even-numbered sections are:

2, 4, 6, 8

So, the number of successfull outcomes is

a=4

Because there are only 4 even-numbered sections.

Therefore, the probability that the spinner lands on an even numbered section is:

p(e)=\frac{a}{n}=\frac{4}{8}=\frac{1}{2}

Carter hikes from the top of a hill that is 120 2/3 feet above sea level down
egoroff_w [7]

Answer:

77 feet

Step-by-step explanation:

Difference is asking for subtraction. The equation would look like:

Top of Hill - Valley = X

(P.S.- 2/3 is equal to . 67)

120.67 - 43.67 = 77

Marking as Brainliest is much appreciated.

I need help on all of these
lord [1]

well #7 is a solution.

y= 9x (4,36)

9 times 4 = 36

36/9=4

so the ordered pair is a solution.

y=3x-5 (7,16)

3 times 7 -5= 16

so once again the ordered pair is a solution.


Hoped this helped.

EASY PLS HELP WILL GIVE BRAINLY If -11 + N = -11, then N is the _____.
Tems11 [23]

Answer:

SteIf -11 + N = -11 then N is the additive inverse because if we do process of elimination (POE) we can cross out C and D because this is a addition problem not a multiplication, and we know its not B because that's like 99 + 0 = 99 set, but instead its A because its just like  -8 + 8 = 0. (If this was not a multiple choice question then tell me)
