Answer:
Step-by-step explanation:
Much depends on how accurate an estimate you want.
If "to the nearest hundred" would be acceptable (it's a lot of work),
Round off 542817 to 542820 and 27398 to 2740. Then you'd want to subtract 2740 from 542820. (Again, it's a lot of work.)
Otherwise round off to the nearest thousand: 543000 - 27000.
Or go to the nearest ten thousand: 540,000 - 30,000 = 510,000 (estimate)
Y = x^2 + 6 doesn’t not belong in the group.
When graphing an x squared it will appear as an parabola (an U shaped graph).
As you can see the rest of the linear equation uses y=mx + b, except for the 3rd one.

Answer:
The slope is -1/2
Step-by-step explanation:
To find the slope you have to use the formula: Δy/Δx OR change in y/change in x.
The change in y for these points is -1 (2-1)
The change in x for these points is 2 (1+2)
Then divide the change in y by the change in x. ( -1 divided by 2)
You will get -0.5 or -1/2 as your final answer for the slope.
