Answer:
Step-by-step explanation:
First, find the <em>rate of change</em> [<em>slope</em>]:
Then, plug the coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope Formula</em> because since you get it done much faster that way. It does not matter which ordered pair you choose:
15 = 2[3] + b
6
_______________________________________________
5 = 2[−2] + b
−4
** You see? I told you it did not matter which ordered pair you choose because you will always get the exact same result.

Answer:
The line of sight distance is 1285.58 feet.
Step-by-step explanation:
The situation is illustrated in the figure attached.
From the figure we see that the altitude difference of the planes and the distance between them form a right triangle with one angle of 40° .
The line of sight between the two planes is the hypotenuse of the triangle.
The altitude difference of the planes is
Therefore, if we call 
the line of sight distance, from trigonometry we have
Therefore, the line of sight distance (x) is 1285.58 feet.
No if it was, the football would keep going up forever and keep going up faster as it was released
physics and common sense tells us that there is air resistance to slow the rise of the football

Answer:
x +4y = -5
Step-by-step explanation:
The equation of the perpendicular line can be found by swapping the x- and y-coefficients and negating one of them. The new constant can be found by substituting the point values into the equation.
3x +12y = 3(-5) +12(0)
3x +12y = -15
We notice that all of the values include a factor of 3. We can divide that out to put the equation in standard form:
x + 4y = -5
