The graph of a linear relationship is shown. Which equation best represents the relationship between x and y in the graph
Finger [1]

Answer:

B.  y = -3/4x + 5/2

Step-by-step explanation:

Take two points from the graph, let's use (-2, 4) and (2, 1):

Find slope:

 m = (y₂ - y₁) / (x₂ - x₁)

     = (1 - 4) / (2 - (-2))

     = -3/4

Find y-intercept using slope above and anyone point:

y = mx + b

(1) = -3/4(2) + b

1 = -3/2 + b

b = 1 + 3/2

b = 5/2

Equation of line using m and b above:

y = mx + b

y = -3/4x + 5/2
