Line a passes through points (6, 10) and (1, 1). Line b is perpendicular to a. What is the slope of line b?

-5/9

Step-by-step explanation:

Slope of line a is,

m = (1-10) / (1-6)

= (-9) / (-5)

= 9/5

Slope of line b is -1/m

-1/m = -1 / (9/5) = -5/9

Slope of line b: -5/9

Step-by-step explanation:

(6,10) and (1,1)

m = (10-1)/(6-1)

m = 9/5

answer: 140

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people

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'.
