7.2x12x0.23= round to the nearest hundredth

7.2 x 12 x 0.23 = 19.872

Now,find the hundredth place. 7 is in the hundredth place.

To round it,look at the number to the right. Remember: 4 and down = less,5 and up = more. Since,2 is 4 and down,your sum to the nearest hundredth is 19.87

There is no graph but what i can say is that 1 is the slope and that -2 is the y- intercept

Your answer should be 1/3. i hope i could ! good luck : )
