Question 88181
You need to choose three numbers for x and solve for y, then graph the points.
y={{{1/2}}}x-1
lets start with making x=1
so solve the equation;
y={{{1/2}}}(1)-1
y={{{1/2}}}-1
y=-{{{1/2}}}
first point = (1,-{{{1/2}}})
now let x=2
y={{{1/2}}}(2)-1
y={{{2/2}}}-1
y=0
Next point (2,0)
for third:
x=4
y={{{1/2}}}(4)-1
y={{{4/2}}}-1
y=2-1
y=1
3rd point (4,1)
