Answer: Driving Speed
Step-by-step explanation:
The Independent variable is the one that is being experimented on to see the effect it will have on the dependent variable.
The Independent variable is adjusted to different levels to see if a relationship exists between these adjustments and a change in the dependent variable.
In this scenario the independent variable would be the speed you drive your car whilst time taken to completely stop is the dependent variable because the speed is the variable being adjusted to see the time taken to completely stop the car.
Slope is calculated as the change in y over the change in x, or rise over run.
The change in y is the difference between the two given y-coordinates: 4 - (-3) = 7
The change in x is the difference between the two given x-coordinates (note that the order of the difference must be the same as the order of the difference of the y values): 1 - 1 = 0
So, 7/0 is the slope, but you cannot divide by 0, so the slope is undefined.
Answer:
B, 60
Step-by-step explanation:
<em>red : blue</em>
3 : 4
3 (20) : 4 (20)
60 : 80
For #1, I have attached the number line.
For #2, I have provided two examples. One shows a different any quality symbol, and the other one shows the same based on absolute values.
For #3, you can see using the number line that -0.5 is the closest to zero.
