Rectangle ABCD is shown below with a line EF drawn through its center. If the rectangle is dilated using a scale factor of 2 and a line is drawn through the center of the new dilated figure, what relationship will that line have with line EF in the drawing below?

see explanation below.

Step-by-step explanation:

Note: We still do not know the orientation of the new line, and the centre of dilation of the rectangle.

A.

If the dilation is about the centre of the rectangle, then the line of image E'F' will remain collinear with line EF.

B.

If the new line is drawn horizontal, it will also be collinear with EF and E'F'.

If the new line is not horizontal, then it will intersect EF and E'F' at the centre.

answer: dead jah

step-by-step explanation:

bullet + jah= dead jah

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
