Firstly, we will find slope of the given lne
we can select any two points from the graph
(-4,-5) and (4,-1)
so, x1=-4 , y1=-5 m x2=4 , y2=-1
now, we can use formula
now, we can plug values
(B)
we are given
line parallel to the nline shown
and we know that
slope of two parallel lines are always equal
so, slope will also be
we have point as (3,4)
now, we can use point slope form of line
we can plug values
we get
(D)
we have point as (-3, 2)
and we know that
slope of perpendicular line is -1/m
so,
now, we can use point slope form of line
we get

Answer:
Δ MAN
reason: ASA
Step-by-step explanation:
if you look at the congruency marks you can see that ∡F ≅ ∡A and we know that ∡N ≅ ∡N
markings also show us that sides UF ≅ MA
therefore, we know two angles and one side for each triangle
-12+3b-1=-5-b
Combine like terms to get:
3b-13=-5-b
Add 13 to both sides:
3b= 8-b
Add b to both sides:
4b=8
Divide both sides by 4:
4b/4=8/4
b=2
Final answer
b=2
