Answer:
scale = ½
center = (2, -5)
Step-by-step explanation:
The distance between A and B is 8
The distance between A' and B is 4
therefore the dilation scale factor is 4/8 = ½
As B and B' have the same x value, the center must also have the same x value of 2
The y value for A is -1
The y value for A' is -3
IF the y value for the center is Y
½(Y - (-1)) = (Y -(-3))
½(Y + 1) = (Y + 3)
½Y + ½ = Y + 3
-2.5 = ½Y
Y = -5
Answer: well search It up 1/10
Step-by-step explanation:
Answer:
y=4
Step-by-step explanation:
-2(y-7)=9y-30
-2y+14=9y-30
-2y-9y=-30-14
-11y=-30-14
-11y=-44
y=4

Answer:
From the points, the x coordinates are the same. With this similarity, the slope of the line would be undefined and it would result as an error to the point-slop formula of the line.
