Y>2x-5 (y=mx + b) 2x is the slope, -5 is the y-intercept
The y-intercept is where the line intersects the y-axis which would be at points (0,-5).
2x is how much the line is rising (the slope of the graph), rise/run. The line will move up 2, and over one for each point. Some of the points on your graph would be (1,-3) (2,-1) (3,1)
