Question 1062151
The point-slope form is:
{{{ y = m*x + b }}} where
{{{ m }}} is the slope
{{{ b }}} is the y-intercept
-----------------------------
given:
{{{ m = -2 }}}
So far I have:
{{{ y = -2x + b }}}
----------------------
The x-intercept occurs where {{{ y = 0 }}},
so you are given the point ( -1,0 )
Plug this point into the equation:
{{{ y = -2x + b }}}
{{{ 0 = -2*(-1) + b }}}
{{{ 0 = 2 + b }}}
{{{ b = -2 }}}
----------------------
The equation is:
{{{ y = -2x - 2 }}}
----------------------
Here's the plot:
