Question 841919
Point-Slope form would be neatest, easiest.

The x-intercept is (-12,0) and slope is -(1/4).


Equation for the line, using point-slope form is {{{y-0=-(1/4)(x-(-12))}}},
{{{y=-(1/4)x-3}}}.
The y-intercept could have also been guessed using the graph, but the choice depends on how well you believe you can read points of the graph.  


If the solid red line means that the line is included with the solution region, then the inequality statement for the graph is {{{highlight(y>=-(1/4)x-3)}}}

This inequality is now in Slope-Intercept Form.
