Answer:
(6,4)
Step-by-step explanation:
Midpoint=((x1+x2)/2 ,(y1+y2)/2)
((10+2)/2 ,(7+1)/2)
(6,4)
x1=10
x2=2
y1=2
y2=1
Answer:

Step-by-step explanation:
Linear equation:
A linear equation has the following format:

In which m is the slope and b is the y-intercept.
Finding the slope:
We have two points: (110, 73.5) and (760, 301).
The slope is given by the change in y divided by the change in x. So
Change in y: 301 - 73.5 = 227.5
Change in x: 760 - 110 = 650
Slope: 
So

Finding the y-intercept:
(760, 301) means that when
. So



So

Add them together
e.g - 5a +6+6a+7
= 11a+13
Answer:
80
Step-by-step explanation:
add
First you need to find the middle number, wich is 75. Since there is no $75, I would go with $80.
