plz help will medal
Which equation represents the graph of the linear function?

A) y=-1/3x+1
B)y=-3x-1
C) y=3x+1
D) y=-3x+1

@dtan5457

Answer 1

D. y=-3x+1

Answer 2

can u explain how u got it

Answer 3

Answer 4

yep d is correct

Answer 5

but how is it d ?

Answer 6

knowing the point (0,1) and (1,-2). plug into Y2-Y1/x2-x1 to find the slope (m).
-2- 1/1-0 = -3. Then plug -2 and -1 into y -y1=m(x - x1) which gives you y-1=-3(x-0)
then solve.. y-1=-3x, -3x+1=y

Answer 7

should be 1 and 0 for the points not -2 and -1
