Answer:
x = -9/2
Step-by-step explanation:
1. Divide 9 by -1/3:
÷
=
· 
= -27
2. Divide both sides by 2:
2(x - 9) = -27

(x - 9) = 
3. Add 9 to both sides:
x = 
(or 4.5 if you need it in decimal form)

Answer:
y=-5/2x+4
Step-by-step explanation:
find the slope by using y2-y1/x2-x1
-1-19/2-(-4)
simplify
-20/8
simplify
-5/2
use slope-intercept form, y=mx+b
since we know the slope, find b
plug in one of the ordered pairs into the equation
-1=(-5/2)(2)+b
simplify
-1= -10/2+b
simplify
-1=-5+b
add 5 to both sides
b=4
plug b into y=-5/2x+b
y=-5/2x+4
