Answer:

Step-by-step explanation:
To find the midpoint, simply use the Midpoint Formula.
The Midpoint Formula states that for two points
and
, the midpoint will be:
.
So, here,
= (-2, -1) and
= (-2, 4). The midpoint is then: 
Thus, the answer is
.
Hope this helps!
U can change it by using the rule of logarithm.
log (10/y)= log10 - log y
35+2x=20+2.50x
subtract 2.50x
35+0.50x=20
subtract 35 frim both sides
0.50x=-15
x=-30
Trendline is drawn over the data points of the scatter plot in order to project which way the plot is directed. If we want to draw the trend line, we should consider the points that will best represent the data. Therefore, the answer to this item is letter C.
