Question

Find the equation of a line that has a slope of –4,

and includes the point (4, –9).


A. y = –4x – 32


B. y = –4x – 25


C. y = –4x – 8


D. y = –4x + 7


E. y = –4x + 40

Answer 1

Answer:

D

Step-by-step explanation:

Finding y int by substituting the points given (say y int is x)

(-9) = 4(-4) + x

(-9) = -16 + x

x = 7

With the y int, you can now write the equation

y = -4x + 7
