Question 43076
I don't know how to shade of these graphs with the PC, so I'll tell you where to shade:
{{{y <= 2x + 9}}}
y-intercept: 9
slope: 2
connect the dots with a solid ({{{y}}} is equal to as well) and shade under (because {{{y}}} is less than)
{{{ graph( 600, 600, -10, 10, -10, 10, 2x + 9) }}}
{{{y >= -6x - 5}}}
y-intercept: -5
slope: -6
connect the dots with a solid ({{{y}}} is equal to as well) and shade above (because {{{y}}} is greater than)
{{{ graph( 600, 600, -10, 10, -10, 10, -6x - 5) }}}
You get a shaded region in the big region at the right right part of the graph.
{{{ graph( 600, 600, -10, 10, -10, 10, 2x + 9, -6x - 5) }}}
