If it equals 12, then it is a point and an answer.
3(0)- 4(-5)-8= 12
(0,-5) is a point!
Next one:
3(4)-4(-2)-8
12+8-8 That equals twelve. (4,-2) is an answer as well!
I am going to quickly plug in the rest of the points, since I think you have the idea. <span>(8,2) 3(8)-4(2)-8= 8 This is not an answer. (-16,-17) 3(-16)-4(-17)-8 = 12 This is answer. (-1,-8) 3 (-1)-4(-8)-8= 21 This is not an answer. (-40,-34) 3(-40)-4(-34)-8= 8 This is not an answer. </span> I hope this helped you!
