if you put the points into the equation y2 - y1/x2 - x1 you'll end up with a zero in the denominator, which indicates a vertical slope. Basically the slope(m) is undefined
It's really easy to tell if your answer is going to be undefined if both the x values are the same (in this case they're both 9)
Answer: 6
Step-by-step explanation: By checking the factors of both numbers, you see that 6 is their greatest common factor.
30: 1, 2, 3, 5, 6, 10, 15, 30
42: 1, 2, 3, 6, 7, 14, 21, 42
Hope this helps!
Answer:
The answer to this equation is 8
Step-by-step explanation:

<u>First: Subtract</u>

meaning that 5 is greater than 4.
You still need another number to make it equal than or greater than or equal to five.

Since 5 minus 4 does equal 1
You need somewhere to divide it from to get 1 so you can add up the 4 to it and get the answer to the equation.
<u>Lastly: Divide</u>


Now, if you do 8/8 which equals 1, 1+4 = 5; Now everything is, <u>equaled</u> up!
<u>So in conclusion...</u>
