You need write the line function's equation this way: y=a.x+b, where "a" is the slope. Well, if we divide both members by 3, we can see that! y=-4/3x+2/3 The slope is -4/3. Good luck! M.
To find the answer, you need to round to the nearest tens. Round 142 to 140 and 1 68 to 160. You know that 1+1=2, and 6+4=10, so 200+100=300 pages read.
