50 pts A line goes through the points (7, 3) and (–1, 5). Write the equation of the line in point-slope form (How did you go from those two points to having the equation in point-slope form?) show work. Thanks

see below

Step-by-step explanation:

First we need to find the slope

m = ( y2-y1)/(x2-x1)

   = ( 5-3)/(-1-7)

   = 2/-8

   = -1/4

Point slope form is

y-y1 = m(x-x1)  where m is the slope and (x1,y1) is a point on the line

y -3 = -1/4( x-7)

or using the other point

y -5 = -1/4( x--1)

y -5 = -1/4( x+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
