Plz explain step by step, i'm taking adv. math (algebra) it's confusing if can't explain, plz at least give right answer ✌

point slope form

y-y1 = m(x-x1)

we need slope   (-3,2) (2,1)

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

   (1-2)/(2--3)

 =-1/5

y-2 = -1/5 (x--3)

y-2 = -1/5(x+3)

Choice D

 point slope form

y-y1 = m(x-x1)

we need slope   (5,40) (10,30)

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

(30-40)/(10-5)

 =-10/5  =-2

y-40 = -2 (x-5)

y-40 =-2x+10

y = -2x+50

Choice C

point slope form

y-y1 = m(x-x1)

we need slope  

 =1/2

y--3 = 1/2 (x-6)

y+3 = 1/2 (x-6)

Choice C
