We know the y intercept is -6 and we know the slope is positive 4 (rise over run) so the equation is y=4x-6 if we plug in a shaded point (I would choose 0,0 for convenience reasons) 0=-6 since -6 is less than 0, the expression would be y≥4x-6
X+3y=3
First add subtract the x
3y=-x+3
Then divide 3
Y=-1/3x+1
