First you need to form a worthy equation using slope-intercept (y=mx+b). Do that by counting the slope and finding the y-intercept. Then you have to choose between < or > to make it more accurate. In order to do so, you would have to pick a point with a point x and y and see wether or not I’m the equation is true when you put it in the blanks. If it’s true then you would shade whichever region the point is. If it’s false then shade the opposite region.
I've done the first four questions. Use this method to answer the rest. For an odd number of objects find the cost of one and multiply by how many you are asked to find.
