Y = mx + b
-3 = 1/2(-2) + b
-3 = -1 + b
b = -2
equation
y = 1/2x - 2
standard form
1/2x - y = 2
or 
x - 2y = 4 
        
             
        
        
        
Answer:






Step-by-step explanation:
step 1
Find the value of x
we know that
 ----> by alternate interior angles
 ----> by alternate interior angles
solve for x
Group terms


step 2
Find the measure of angle a
we know that
 ----> by vertical angles
 ----> by vertical angles
substitute the value of x

step 3
Find the measure of angle b
we know that
 ----> by supplementary angles (form a linear pair)
 ----> by supplementary angles (form a linear pair)
we have

substitute


step 4
Find the measure of angle c
we know that
 ----> by vertical angles
 ----> by vertical angles
we have

therefore

step 5
Find the measure of angle d
we know that
 ----> by corresponding angles
 ----> by corresponding angles
we have

therefore

step 6
Find the measure of angle e
we know that
 ----> by alternate exterior angles
 ----> by alternate exterior angles
we have

therefore

step 7
Find the measure of angle f
we know that
 ----> by vertical angles
 ----> by vertical angles
we have

therefore
