Please help! A line contains the points (-7, -2) and (-9, y). Find the value of y so that the line has a slope of
−3/5

x1=x

x2=3

y1=5

Y2=9

And dy/dx=2

therefore, the solution for x is

2=(9−3)/(5−x)=6/(5−x)

2(5−x)=6

Dividing both sides by the coefficient of (5-x)

5−x=3

then x=5−3=2

Therefore x=2

to solve for y

3=(y−(−5))/(4−(−3))=(y+5)/(4+3)

3=(y+5)/7

Multiplying both sides by 7

21=y+5

y=21−5

y=16

Therefore

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.

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48
