Question

Plz explain step by step, I'm taking Adv. Math (Algebra) It's confusing

If can't explain, plz at least give right answer ✌

Answer 1

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
