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:
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

Answer:
5.5 miles per hour
Step-by-step explanation:
Since he travels a total of 55 miles in 10 hours, you need to divide.
55/10 = 5.5
total hours/total miles = miles per hour
Answer: 6
The sides are equal.
Thus
$JP=x+2=4+2=\boxed{6}$
