What is slope of the line?
y=-6+4.5x
1)-6
2)-4.5
3)4.5
4)6

Explanation:

The equation y = -6 + 4.5x is the same as y = 4.5x + (-6)

Compare this to y = mx + b and we see that

m = 4.5 is the slope

b = -6 is the y intercept.

note: we can write y = 4.5x + (-6) as y = 4.5x - 6

step-by-step explanation:

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.
