The 1 is in the hundreds place good luck!!!
From the given table, the points can be written as : (6,7.55) , (12,7.85), (18, 8.15) and (24, 8.45)
Slope 
m = 
m = 0.05
slope intercept form of line = 
We plug m = 0.05, x = 6 and y = 7.55 and find c.

c= 7.25
Required equation:
... Answer
Answer:
y = 1/2x + 1
Step-by-step explanation:
Slope: 1/2
Point: (2,2)
y-intercept: 2 - (1/2)(2) = 2 - 1 = 1
Slope is 2 and the y intercept is 4
slope intercept form equation, y = mx + b
answer, y = -2x + 4
