Answer:
<em>y-9=0(x-6)</em>
<em>Or, equivalently: y=9</em>
<em>This represents a horizontal line</em>
Step-by-step explanation:
<em>Equation of the line</em>
The point-slope form of the equation of a line is:
Where m is the slope and (h,k) is a point through which the line passes.
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
The points are (6,9) and (7,9). These points dfine a horizontal line, as we'll see later.
The slope is:
m=0
Now compute the equation in point-slope form:
y-9=0(x-6)
Solving for y:
y=9
This represents a horizontal line

X = velocity of plane
y = velocity of wind
x - y = 1680/5 = 336 mph .....(1) [ plane flying against the wind]
&
x + y = 1680/4 = 420 mph....(2) [ plane flying with the wind]
Adding (1) and (2) to eliminate y gives
2x = 756
x = 378 mph is the speed of the plane with no wind.

Slope is -2
