Identify the slope of the line for the equation y = 10x + 3.
Mrrafil [7]

Answer:

D) 10

Step-by-step explanation:

The slope of the line y=10x+3 is 10 because in the slope form y=mxtb m represents the slope. In this case 10 is m, therefore the slope is 10. This mean the slope rises 10 units and runs 1 unit since slope is also known as rise/run.

Help me with this question this was supposed to be due yesterday!
Inessa05 [86]

Answer: Both the mean and median decreased.

Step-by-step explanation:

The addition of the 500 lb baby elephant will have a huge impact on the mean, since you'll be finding the average (adding all numbers then dividing). So the only logical answer would be the chosen. The median will most likely either decrease or stay the same, but since staying the same isn't an option for the median, it's most likely going to be decrease.

[I do apologize in advance if it's wrong, and next time try submitting work on time :)) Hope I helped!]
