Question 1121114
Let {{{ m }}} = the undefined slope
Let {{{ b }}} = the y-intercept
{{{ y = m*x + b }}}
Plug ( 1, -4 ) into this equation
{{{ -4 = m*1 + b }}}
{{{ b = -m - 4 }}}
Plug this result into the general equation above
{{{ y = m*x - m - 4 }}}
Check:
Does it go through ( 1, -4 ) ?
{{{ y = m*1 - m - 4 }}}
{{{ y = -4 }}}
OK
