Answer:
Using the point-slope form:
The equation of the line is given by:
.....[1] where
m is the slope of the line and
is the point on the line.
As per the statement:
Given: Two points i,e (34, 76) and (42, 91)
First calculate slope(m):
Slope is given by:

Substitute the given values we have;

Now, substitute the value of m and (34, 76) in [1] we have;
Using distributive property: 
Add 76 to both sides we get;
Therefore, the equation of the trend line is:
Answer:
5 4/9 - 2 5/9= 26/9 or 2 8/9
Step-by-step explanation:
The answer is A because both numbers can be divided by 6 to get 5 : 9
Answer:
The coordinates are (6.5, 1.7).
Step-by-step explanation:
The difference between A and B's x-coordinate is 15. 7/10 of this is 10.5, which added to -4 gives us an x-coordinate of 6.5.
The difference between A and B's y-coordinate is 11. 7/10 of this is 7.7, which added to -6 gives us a y-coordinate of 1.7.
Therefore, the coordinates are (6.5, 1.7).
