Find the gradient of lines A and B

Line A Gradient: 2

Lime B Gradient: -1

Step-by-step explanation:

✔️Gradient for line A using two points on line A, (0, 1) and (1, 3):

Gradient of line A = 2

✔️Gradient for line B using two points on line B, (5, 0) and (3, 2):

Gradient of line B = -1

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
