First to answer correctly get brainleist! 1 the equation of the linear regression line represents the relationship between the number of laps a person can swim, x, and the number of minutes a person can run, y. yˆ=5/2x+6 what does the slope of the line represent? for every 5 laps that a person can swim, the number of minutes they can run decreases by 2. for every 2 laps that a person can swim, the number of minutes they can run decreases by 5. for every 2 laps that a person can swim, the number of minutes they can run increases by 5. for every 5 laps that a person can swim, the number of minutes they can run increases by 2.

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

i think that you should ask google for the answer to that problem because if we don't know it google does
