I WILL GIVE A (DUE SOON) is the given ordered pair a solution of the system of inequalities?

1. (1,19)

y ≤ 7x-13

y > 3x+6

2. (4,10)

9x-y≥ 23

5x+0.2y≥ 20

3. (-2,40)

Y> -13x+29

y≤ 9x+11

Solve each inequality by graphing.

4. y<2x+4

-3x-2y+6

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

i have no idea just need points sorry
