Help A line with a slope of -2 passes through the points (-4, 7) and
(0, n). What is the value of n?

n = -1

Step-by-step explanation:

Use the equation y=mx + b

m (slope) = -2

x (x coordinate) = -4

y (y coordinate) = 7

You are solving for b.

Plug in for the given values:

7 = -2(-4) + b

7 = 8 + b

-1 = b (Minus both sides by 8)

y= -2x -1

Therefore, n = -1

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.
