You can
put this solution on YOUR website!You need to choose three numbers for x and solve for y, then graph the points.
y=

x-1
lets start with making x=1
so solve the equation;
y=

(1)-1
y=

-1
y=-

first point = (1,-

)
now let x=2
y=

(2)-1
y=

-1
y=0
Next point (2,0)
for third:
x=4
y=

(4)-1
y=

-1
y=2-1
y=1
3rd point (4,1)
