Which of the following is the slope and y-intercept of the graph -y= -0.9x + 4 ?

slope =  0.9, y- intercept = - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange - y = - 0.9x + 4 into this form

Multiply through by - 1

y = 0.9x - 4 ← in slope- intercept form

with slope m = 0.9 and y- intercept c = - 4

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.
