Option B:
The equation of the line given is 
.
Solution:
Take any two points on the line of the graph.
Let the points be (0, 2) and (3, 3).
Slope of the line:
Using point-slope formula,
Add 2 on both sides of the equation.
The equation of the line given is .
Hence Option B is the correct answer.
Take 4485 and divide by 1.609. Meaning it is about 2787.4 or just 2787 miles.
We know that AB is perpendicular to CD. (that was given)
Perpendicular angles are 90 degrees because two straight lines (180) crossed make 4 90 degree angles.
180+180=360
90*4=360 See the similarities?
7x+6= 90 degrees
Subtract 6 on both sides.
7x=84
Divide both sides by 7.
x=12
"B" is the correct answer.
I hope this helps!
