Question 259229
We start with x-intercept, which is a point at (4,0)
From here we find the slope using
{{{m = (y2-y1)/(x2-x1)}}}
and our coordinates and get
{{{m = (0-(-3))/(4-(-2))}}}
which is simply
{{{ m = 3/6}}}
or
{{{m = 1/2}}}
--
Next we use y = mx +b to get
{{{0 = (1/2)*4 + b}}}
solving for b we get
{{{b = -2}}}
--
Our equation is 
{{{y = (1/2)x  - 2}}}
