Graphs of linear functions

The blue line, y=12x−3y=\frac{1}{2}x-3y=​2​​1​​x−3 and the red line, y=−x+5y=-x+5y=−x+5 are both linear functions.  The blue line has a positive slope of 12\frac{1}{2}​2​​1​​ and a yyy-intercept of −3-3−3; the red line has a negative slope of −1-1−1 and a yyy-intercept of 555.
