Answer:

y=-2/3x-3

Step-by-step explanation:

y-y1=m(x-x1)

y-(-1)=-2/3(x-(-3))

y+1=-2/3(x+3)

y=-2/3x-6/3-1

y=-2/3x-2-1

y=-2/3x-3

Answer:

7

Step-by-step explanation:

line in the middle is an angle bisector

14/6 = 21 / 3x - 12

first, cross multiply

14 (3x - 12) = 6*21

Remove the brackets

42x - 168 = 126

Add 168 to both sides

42x = 168 + 126

Combine

42x = 294

Divide by 42

x = 294/42

x = 7
