Question 955124
You are given 2 points:
( 1,0 )
( 0,-1 )
---------
You can plug these points into
the general equation:
{{{ y = m*x + b }}}
( 1,0 )
{{{ 0 = m*1 + b }}}
(1) {{{ m = -b }}}
--------------
( 0,-1 )
{{{ y = m*x + b }}}
{{{ -1 = m*0 + b }}}
(2) {{{ b = -1 }}}
---------------
Substituting:
(1) {{{ m = -b }}}
(1) {{{ m = -(-1) }}}
(1) {{{ m = 1 }}}
---------------
The equation is:
{{{ y = 1*x - 1 }}}
{{{ y = x - 1 }}}
---------------
Here's the plot:
