4. y < -1/2x+6
slope-intercept form:
y= mx+b
Where:
m= slope ( rise y over run x )
b= y-intercept ( where the function crosses the y-axis)
For our case:
m= -1/2 ( for every 2 units to the right along the x-axis, the function goes down 1 unit)
b= 6
Since y < ( less than) the solution is below the function , and the line is represented with a dashed line.,
