Answer:
Line A and Line C are parallel
Step-by-step explanation:
<u>Slope Equation: </u>
<u>Step 1: Find the slope of the first line</u>
Line a passes through (-1, -2) and (1, 0).
<u>Step 2: Find the slope of the second line</u>
Line b passes through (4, 2) and (2, -2).
<u>Step 3: Find the slope of the third line.</u>
Line c passes through (0, 2) and (-1, 1).
Answer: Line A and Line C are parallel
An=a1+d(n-1)
an=nth term
a1=first term, when n=1
d=common differnce=amount each term increases by
n=which one
so
when n=1, an=40
so a1=40
it seems to increas by 7 each time
an=40+7(n-1)
explicit formula is expanded
an=40+7n-7
an=33+7n is the formula
the domain is natural numbers because you can't have the -3rd term or the 0th term or the 3.24th term
domain is natural numbers
the formula is
