Answer:
Step-by-step explanation:
θ is the angle the ladder makes with the ground.
θ = arcsin(13.8/14) ≈ 80.3° > 78°
The ladder is not safe at that height and angle.
Slope: 1/2
y int: 7

(3,-4) is your x and y. Plug it in the equation so,
For x,
2x+3y=3
2x+3(-4)=3
2x-12=3
2x=12+3
2x=15
2x/2=15/2
x=7.5
For y,
2(3)+3y=3
6+3y=3
3y=-6+3
3y=-3
3y/3=-3/3
y= -1
Sorry don't know the answer
Subtract 6x from 9x
-15=3x-6
add 6 to both sides
-9=3x
divide 3 from both sides and -3=x
