equation in slope-intercept form: where is a slope and is y-intercept
Line 1
|
|
|
...use given and to find and
if and , we have
...solve for
....eq.1
if and , we have
...solve for
....eq.2
since eq.1 and eq.2 have same left sides, right sides must be equal too; so, we have
...solve for
go back to eq.1, plug in
....eq.1
so, Line 1:
Line 2
|

| -> this shows you that line 2 passes through origin; so, y-intercept
use that and other given and values to find
...solve for
so, Line 2:
