The is The 103.8 Cause Of the math is correct
16.24 divided by 0.14 equals 116 i hope this helps if not sorry :)
You see what the average is in each class. (Divid students and classes) and add them together and divid by four. You should get 18 if you round to the whole number.
"Goes downwards from left to right" is basically saying that the slope of this line is negative. We go downhill from left to right.
y = 2x+5 has a positive slope because m = 2 is the slope (b = 5 is the y intercept)
So choice A is out
Similarly choice B is eliminated as well because the slope is also m = 2
Choice C is false as well. The slope here is m = 2 (think of y = 2x as y = 2x+0)
The only choice with a negative slope is choice D. The slope is m = -2
This is why the answer is choice D
Side Note: I'm using slope intercept form y = mx+b where m is the slope and b is the y intercept
