Write an equation in point-slope form and slope-intercept form for each line. 1. passes through (4, 7), slope = 2
2. passes through (–2, –1), slope = 4
3. passes through (8, –4), slope = 1/2

y=2x-1

y-7=2(x-4)

2x-y-1

//

y=4x+7

y--1=4(x--2) = y+1=4(x+2)

4x-y+7

//

y=1/2x-8

y--4=1(x-8) = y+4=1(x-8)

1x-y-12

here u go

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

66.666666667%

step-by-step explanation:

divide 150 by 100

divide 100 by 1.5

there you go!
