Question 937658
(-5,6)
(3,-1)
slope = ( change in y ) / ( change in x )
Let {{{ m }}} = slope
{{{ m = ( 6 -(-1) ) / ( -5 - 3 ) }}}
{{{ m = ( 6 + 1 ) / (-8) }}}
{{{ m = -7/8 }}}
-----------------
check:
The general form is:
{{{ y = m*x + b }}}
{{{ y = (-7/8)*x + b }}}
----------------------
(-5,6)
{{{ 6 = (-7/8)*(-5) + b }}}
{{{ 6 = 35/8 + b }}}
{{{ b = 48/8 - 35/8 }}}
{{{ b = 13/8 }}}
------------------
{{{ y = (-7/8)*x + 13/8 }}}
Here's the plot:
{{{ graph( 400, 400, -10, 10, -10, 10, (-7/8)*x + 13/8 ) }}}
Looks about right
