Line ab contains points a (1, 2) and b (−2, 6). the slope of line ab is (4 points)

a
zero

b
undefined

c
positive

d
negative

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

the 3rd on is correct
