The answer is A
start by isolating the y variable
the rest of the work is shown here
F=32+1.8c. This is in slope intercept form, so 32 is the Y intercept, and the slope is 1.8(9/5).
Answer:
y=3x-2
Step-by-step explanation:
The formula for slope is y=mx=b
You can find the slope by finding two points that lie on the line (1,1) & (0,-2)
The formula for slope is 
You plug the values in and you get 
Simplify and you get 3
The slope is 3
The y-intercept (b) is -2
Note that 6 inches is half a foot, so if its 4ft. then 1/2 of a foot goes in 8 times which means that the scale factor is 8. :)
The answer to this problem is 3(2x+1)
