Question

How would you graph the result of -3 plus 5 as a point on the number line?

Answer 1

Draw the number line (horizontally) and mark -3; To add +5 go 5 marks to the right; Either mark each step right as a little arc above the line, or mark one large arc from the -3 to 5 marks to its right: _________________________________________________ _____________-_____-_____-____-_____-_____________ ____________/_\___/_\___/_\___/_\___/_\____________ ___________/___\_/___\_/___\_/___\_/___\___________ -----+-----+-----+-----+-----+-----+-----+-----+----- __________-3_______________0__________2__________ __________________________________________________ or __________________________________________________ ______________--------------------------______________ _____________/______________________\_____________ ____________/________________________\____________ ___________/__________________________\___________ -----+-----+-----+-----+-----+-----+-----+-----+----- __________-3_______________0__________2__________ __________________________________________________ You could put an arrow head at the right hand end of each arc.
