How do you graph #y>=1/2x-5#?
See a solution process below:
First, solve this as a equality for two values of
We can then plot the two points on the gird.
Then, draw a solid line through the two points. We will use a solid line because the inequality is "greater than or equal to". If the inequality was just "greater than" we would use a dashed line.
Finally, because this is a greater than or greater than or equal to inequality we shade the area above the line.
