How do I do this math question?
Lynna [10]

Answer: You just need to draw a line

Step-by-step explanation: Place a dot on positive 2 on the y-axis, then go down 7 and 1 to the right. If it doesn’t go all the way down, make your own point to make it seem like it will land where it has to be and connect it to the positive 2. It has to be a straight line
