What is the y-intercept of the line shown on the graph that represents a proportional relationship?
a) y = −4
b) y = 0
c) y = 1
d) y = 2
someone i think its b!
also giving 25 points!

B.

Step-by-step explanation:

We have been given a diagram. We are asked to choose the y-intercept of the line that represents a proportional relationship.

We know that a proportional equation is in form , where k is constant of proportionality.

We also know that a proportional equation passes through the origin (0,0).

Therefore, the y-intercept of the equation would be and option B is the correct choice.

1/3 + 1/5 = 8/15.

step-by-step explanation:

hope it

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'.
