Which equation is the equation of the line, in point-slope form, that has a slope of −4 and passes through the point (7, 1) ? A. y−1=−4(x−7)
B. y−7=4(x−1)
C. y−1=−4(x+7)
D. y−7=−4(x−1)

y - 1 = -4(x - 7)

General Formulas and Concepts:

Algebra I

Point-Slope Form: y - y₁ = m(x - x₁)  

Step-by-step explanation:

Step 1: Define

Slope m = -4

Point (7, 1)

Step 2: Write Equation

Plug in variables into the general formula.

y - 1 = -4(x - 7)

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.
