Which of the lines below has an undefined slope?
2 answers:
The answer is b because once it's a vertical line it does not have a run for y coordinate
Answer:
The correct option is B.
Step-by-step explanation:
The slope of a line is calculated as
The slope of line is undefined if there is no change in the values of x. It is possible only in the case of vertical line.
Graph B represents a vertical line. So the slope of the line in graph B is
The slope of line B is undefined, therefore the correct option is B.

Answer:
Let the two supplementary angles be
we know sum of two supplementary angles is 180
2x + 3x = 180
5x = 180
x = 180/5
x = 36
2*36 = 72
3*36 = 108
Therefore the two supplementary angles are 72 and 108
B is the answer hope this helps :)
2 * 10^2
Divide the first numbers, which are 6 and 3, to get 2. Then, subtract the powers of the exponents, which are 5 and 3, to get 2.
(-7,-5)
Step-by-step explanation:
3x-8y = 19
minus
3x + 5y = -46
0x - 13y = 65
- 13y = 65
÷-13
y = - 5
Substitute y = - 5 into one of the functions:
3x-8y = 19
-8 x - 5 = 40
3x + 40 =19
-40
3x. = - 21
÷3
x= - 7
Solution is (-7,-5)
Hope this helps!
