Question

PLEASE PLEASE PLEASE HELP, ILL GIVE 98 POINTS ( show your work)

Answer 1

Answer:

Step-by-step explanation:

The points given are: (1,-4), (7,-7), (13,-10), (19,-13)

They line up to a straight line with slope:

((-4)-(-7))/(1-7) = 3/-6 = -1/2

The equation in point-slope form is

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

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

A is the right answer.

Answer 2

Answer:

Step-by-step explanation:

there is a linear relationship

from the table, x changes by +6, y changes by -3 every time

so that means the slope is constant i.e. its a straight line

slope=(y2-y1)/(x2-x1)=-3/6

= -1/2

take the 1st pt, ( 1, -4 )

(y-(-4)) = slop * (x-1)

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

ans is A
