The coordinates of point J' is (0,-2) which represent the image of J
let J (x,y) ⇒⇒⇒⇒ J' (x',y') = (0 , -2 )
The graph was dilated according to the rule:
(x,y) ⇒⇒⇒ ( 0.5x , 0.5y)
so, for the x coordinate
∴ x' = 0.5 x ⇒⇒⇒ x = 2x' = 2*0 = 0
for the y coordinate
y' = 0.5 y ⇒⇒⇒ y = 2y' = 2 * (-2) = -4
∴ The coordinates of J is ( 0 , -4 )
∴ The correct answer is the first option
Answer:
the value of a is 3-y /b I think
Rate is closer to a constant pattern , example: I'm walking at a rate of 2 miles an hour.
Ratio is related to the proportion of two or more objects, example: The ratio for a perfect tang juice is 1 packet of tang dust thingy for 1.5 liters of water.
Hope it helps :)
