Hey there! :D
Just plug in the values of x.
y= 1/2(-5)-2
y= -2.5-2
y=-4.5
First point: (-5, -4.5)
y= 1/2(-2)-2
y=-1-2
y=-3
Second point: (-2, -3)
y= 1/2(1)-2
y =.5-2
y=-1.5
Third point: (1,-1.5)
y= 1/2(3)-2
y= 1.5-2
y=-.5
Fourth point: (3, -0.5)
y= 1/2(6)-2
y=3-2
y=1
Fifth point: (6,1)
I hope this helps!
