HELP!!

In 5-8, write an equation of the trend line in slope-intercept form.

First, find out the y-intercept(s).

For 5, it is 6. For 6, it is 150. For 7, it is 20. For 8, it is 0.

Now we need to find the slopes.

For 5, it goes down one and right 2, so it would be -1/2 (rise/run).

For 6, it goes up 100 and right 2, so it would be 100/2 (rise/run) or 50.

For 7, it goes up 10 and right 3, so it would be 10/3 (rise/run).

For 8, it goes up 25 and right 1, so it would be 25/1 (rise/run) or 25.

Then you plug into the equation: y = mx + b

5: y = -1/2x + 6.

6: y = 50x + 150.

7: y = 10/3 + 20.

8: y = 25x + 0 which would be y = 25x (since add 0 is useless).

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

it is 570
