Find slope of the line giving brianly make sure to explain

D 6

Step-by-step explanation:

To find the slop you do rise/run. You find where a point is exactly on a line and find the rise and the run difference. In this question the two easiest points to figure out is (0,-3) and (1,3). The rise (or the difference in y) is 6 and the run (or difference in x ) is 1. 6/1=6.

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
