-4x + 2y = -8 in slope interception form (y= mx + b )

y=2x-4

Step-by-step explanation:

so we just have to rearrange this to

2y=4x-8

we can do this by adding 4x to both sides

then we divide by 2

y=2x-4

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

50-38=12
