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:
You have to get y by its self but don’t add 4x to 104 put it as 2y=104+4x then divide them all by 2
