Use formula : Y-y1=m(x-x1)
(x1,y1) = the points given in each situation

6. Y-0=1(x-2)
Y=x-2 or x-y-2=0

7. Y-(-1)= -1/3(x-(-3))
Y+1= -1/3x + 1
3y=-x or x+3y=0

8.Y-4=3(x-5)
Y-4= 3x - 15
Y=3x -11 or 3x-y-11=0

[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] sinθ = opposite over hypotenuse

Step-by-step explanation:

Step 1: Identify

Angle θ = A

Opposite Leg = 27

Hypotenuse = 42

Step 2: Solve for A

Substitute [sine]: sinA = 27/42
Simplify: sinA = 9/14
Trig inverse: A = sin⁻¹(9/14)
Evaluate: A = 40.0052°
Round: A ≈ 40°

Can 1,1,2 be the length is a triangle

Sholpan [36]

Alright, so in order to find this, you will nee to use the Triangle Inequality Theorem.
We’ll make the values = to variables to make it easier. a=1 b=1 c=2
All of the inequities need to be true.
a+b>c
b+c>a
c+a>b
Now replace the variables.
1+1>2 2>2 (False)
1+2>1 3>1 (True)
1+2>1 3>1 (True)
Since one is false, 1,1, and 2 cannot make a triangle.
