You can put this solution on YOUR website!

as you can see from the graph, we have dashed line and shaded area is all to the left
so, we need equation of that line and we can find it using 2 points on it

points are:
(0,7) and (4,-5)

then a slope is
m=%28-5-7%29%2F%284-0%29
m=-12%2F4
m=-3

equation of a line with given slope and point is

y-y1=m%28x-x1%29
substitute m=-3 , y1=7, and x1=0
y-7=-3%28x-0%29
y=-3x%2B7

since this line is not part of solution (because is dashed), inequality will be

y%3C-3x%2B7
or in standard form
3x%2By%3C7
