The answer would 12. Think of ratios as fractions. 1/2 = 6/12 So, 6:12
Of means multiplication. So the question is 1/3 X 1 1/2. First make 1 1/2 improper: 3/2. Then multiply the numerators (top numbers) and denominaters (bottom numbers): 1x3=3, 3x2=6, =3/6. Now simplify 3/6=1/2. Then multiply that by 2, since he used 2 pieces: 1/2x2=1. John used 1 meter :)
The slope is zero because the rise (8-8) is zero, and the line will be horizontal because lines with a slope of zero are horizontal.
