the line is the opposite reciprocal of the "parent line". for example, 2 would be -1/2. So, (1-2)/(15-4)=1/11(slope). so the slope would be -11, which means y=-11x+b

first of all:
parallel lines have equal slope
so first find the slope of the line that passes thru the 2 points:
slope = change in y/change in x
slope = (2-1)/(4-15) = 1/-11
slope = -1/11
hope this helps!

(15,1) and (4,2) are the coordinates of a line....
parallel essentially means having the same slope thus the slope for the given line is equal to the slope of the parallel line...
There are two ways of determining the slope....
1)
find the slope of the given line using definition of slope....
m = rise over run = y/x = (2-1)/(4-15) = -1/11
2) find the slope using your knowledge of a line.... y = mx+b
(y-y1)/(x-x1) = m --> y = m(x-x1) + y1 or b
thus:
2 = m(-11) +1
m = 2 - 1 / -11
m = - 1/11

-0.0909 it is the slope of the line that passes interior the direction of the factors 15,a million and four,2. The vertical distinction divided via the horizontal distinction. Any line it is parallel to this line might have an identical slope.

the slope is the change in Y / change in X
Change in Y = 1-2
Change in x = 15 -4
I'm sure you can do the rest.

take y-y over x-x
2-1/4 -15
and you get -1/11
