The lines shown below are parallel. if the green line has a slope of -1/2, what is the slope of the red line? a.2 b.-1/2 c.-2 d.1/2

The slope of red line is

B is correct.

Step-by-step explanation:

Two lines are parallel. Two lines shown by color green and red line.

As we know if lines are parallel then their slope is equal.

W are given green line is parallel to red line.

The slope of green line is

But The slope of red line = slope of green line.

Slope of red line

Hence, The slope of red line is

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
