For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis

We have the following points:

Substituting the values:
Thus, the line is of the form:

We substitute one of the points and find "b":

Finally we have to:

Answer:
The equation es 
Answer:
2,265.60 ft/hr
Step-by-step explanation:
168ft/6min = 28ft/min * 60min= 1,680ft/hr
472ft/12.5min= 37.76ft/min * 60min= 2,265.60ft/hr
4 thousands = 4000 7 hundreds = 700
4000 + 700 = 4,700
6/20 in simplest form is 3/10
x = –3, then –x = –(–3) = +3,
