Slope of the line: -3/4

y-intercept: (0, - 1.75)

Answer

Slop=-3/4, y intercept =-7/4

Step-by-step explanation:

I'm assuming that you actually need to show work for this, so here is how you do this problem.

Start by isolating y on one side of the equation.

3x+4y=-7 Becomes y=-3/4x-7/4

Since this is now in Y=mx+b form, we just match up the values.

m=slope --> m=-3/4

b=y intercept --> b=-7/4

The answer to your question is 1052 ft

Step-by-step explanation:

Data

∠A = 50°

∠B = 78°

Distance from A to the ground = 1000 ft

Process

1.- To solve this problem use trigonometric functions. The trigonometric function that relates the Opposite side and the adjacent side is tangent.

              tan Ф = Opposite side / adjacent side

-Solve for adjacent side

               Adjacent side = Opposite side / tan Ф

-For the left triangle

              Adjacent side = 1000 / tan 50

-Simplification

              Adjacent side = 839.1 ft

2.- Calculate the adjacent side of the right triangle

              Adjacent side = 1000/ tan 78

-Simplification

             Adjacent side = 1000 / 4.7

-Result

             Adjacent side = 212.56

3.- Distance from A to B

Distance = 839.1 + 212.56

              = 1051.7 ft ≈ 1052 ft
