Question 1085865: I need an example of how to solve this because I am not solving this correctly. This is my work (which is wrong)because I want it in y=mx+b so that I can get the slope (m) but im only able to solve for x.. please help.
9y+5x>=9y-20
9y+5x=9y-20
+9y
5x=-20
x=-20/5
x=-4, -4,0 but how do I then get the slope so I can graph this?
Below is the exact wording to the question:
Graph the solution set of the following linear inequality:
9y+5x>=9y-20

9y%2B5x%3E=9y-20
it in y=mx%2Bb means solve for y
in your case we have 9y on both sides which cancel each other, so
cross%289y%29%2B5x%3E=cross%289y%29-20
5x%3E=-20
x%3E=-20%2F5
x%3E=-4-> so, you have solution set for x: [-4, infinity)
but, for 9y%2B5x%3E=9y-20 there is no solution and there is no x-intercepts

The INEQUALITY results in: x+%3E=+-+4 <====== You are correct. Good job!!
This INEQUALITY has an UNDEFINED slope, and as such, represents a SOLID (UNBROKEN) VERTICAL line at x = - 4, and which is parallel to the y-axis.
Now, since the INEQUALITY is: x+%3E=+-+4, you need to shade to the right of this VERTICAL LINE.
That's all!!
