Which of the following is true?

Answer choice #4 (m is positive)

Step-by-step explanation:

[#1 is upper-left, #2 is upper right, #3 is lower left, and #4 is lower-right]

If the slope was m=0 then the line would be horizontal, and if the slope was undefined, then the line would be vertical. However, answer choice #1 and #3 have the incorrect answers and the correct answer is the answer for #3 and #1 respectively. This means that the answer to #1 is #3's answer and the answer to #3 is #1's answer. So neither have their correct answer.

The picture for both answer's #2 and #4 are the same. However, #2 says that the slope is negative, and #4 says that the slope is positive.

Let's take a loot at the picture for #2 and #4. It shows a line that is ascending diagonally to the right. A slope that is ascending right-way is a positive slope. This means that #2 is incorrect since it says that the picture has a negative slope, even though the slope ascends to the right. If #2 was correct, the picture would have a slope ascending to the left, but since it doesn't, it's wrong. Therefore, by process of elimination, the correct answer is choice #4: m is positive. Hope that this helps explain thoroughly enough!

Answer choice 4. M is postive

Step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
