Slope = (y2 - y1) / (x2 - x1)
(-1,3)....x1 = -1 and y1 = 3
(1,-1) ...x2 = 1 and y2 = -1
now we sub
slope = (-1 - 3) / (1 - (-1) = -4/2 = -1/2 <==
Answer:
So we have 3 pounds of apples. 3 pounds= 6 dollars. This means for 1 pound, it costs 2 dollars. So since 1 pound is 2 dollars, take 10 pounds and multiply it by 2, you get 20 dollars. So the cost of 10 pounds is 20 dollars. If you wanna do it the short way, the cost is always twice the amount of the pounds.
The ratio the point P partition the directed line segment from M to N is 9:2
<u>Step-by-step explanation:</u>
Let the total distance between M and N be 'd'
Point P distance from M = (9/11) d
Point P distance from N = (1 - 9/11) d
= (2/11) d
The ratio of the distance = (9/11) d / (2/11) d
= 9/2
= 9:2
The ratio the point P partition the directed line segment from M to N is 9:2
