Answer:
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.
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
