X - y = 0.85
x + y = 1
----------------add
2x = 1.85
x = 1.85/2
x = 0.925
x + y = 1
0.925 + y = 1
y = 1 - 0.925
y = 0.075
so ur 2 numbers are : 0.925 and 0.075
-1/3, -1/5, 0, 1/8
u put the negative numbers to the left and positive ones to the right then since -1/3 is more negative than -1/5, -1/3 goes to the left and-1/5 goes next to it and then 0 and since 1/8 is the biggest it goes to the right
First, you need to know what equation form you need to write: point slope, slope-intercept, etc. Considering this case, you need to know the slope, then you must know the y-intercept, and and write like this: ( my example here is for the SLOPE- INTERCEPT form) y=slope times X + y-intercept.
Hope it helps :D
