Examine the following graph on the line
Lorico [155]

Answer:

B. y - 0 = -⅓(x + 2)

Step-by-step explanation:

First, find the slope of the line using two points in the line, (-5, 1) and (-2, 0):

Slope (m) = ∆y/∆x = -⅓

To find the equation in point-slope form, substitute (a, b) = (-2 0), and m = -⅓ into y - b = m(x - a)

Thus:

y - 0 = -⅓(x -(-2))

y - 0 = -⅓(x + 2)
