Answer:
the second choice is correct
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y =
x - 9 is in this form
with slope m = 
• Parallel lines have equal slopes, hence
y =
x + c ← is the partial equation of the parallel line
To find c substitute (- 8, - 18) into the partial equation
- 18 = - 6 + c ⇒ c = - 18 + 6 = - 12
y =
x - 12 ← equation of parallel line
Angles 1, 3, 5, and 7 each equal 50 degrees
180 - 50 = 130
Angles 2, 4, 6 and 8 each equal 130 degrees
Answer:2.25
Step-by-step explanation:it just is
D
Step-by-step explanation:
2/6 is litterally right there cause it has seven lines and tge 0 doesnt count
6+8+b is assuming because it’s asking for the total weight
