Use the given conditions to write an equation for the line in point-slope form and in slope-intercept form. passing through (minus−22,minus−44) and parallel to the line whose equation is y equals negative 2 x plus 4y=−2x+4 write an equation for the line in point-slope form. y plus 4 equals negative 2 (x minus 4 )+4=−2(x−4) (simplify your answer. use integers or fractions for any numbers in the equation.) write an equation for the line in slope-intercept form.

Step-by-step explanation:
y=-2x+4
eq. of any line parallel to given line is
y=-2x+c
Because it passes through (-22,-44)
-44=-2*(-22)+c
c=-44-44=-88
eq. of reqd. line is y=-2x-88

A dilation of 2 about the origin.
Step-by-step explanation:
You can see in the original figure the points are half the points of the transformed figure.
For example the coordinates of H are (0.5,0)
The coordinates of H' are (1,0)
Since 0.5 * 2 = 1
There is a dilation of 2 about the origin.
