Plz answer what is the equation of the function shown in the graph? a. y = x + 1 b. y = 2 x - 1 c. y = 3 x - 1 d. y = 2 x + 1

The line passes through the points
(x₁,y₁) = (1,2)
(x₂,y₂) = (0,-1)

First, find the slope of the line
It could be determined using this following formula
m = 
m =
m =
m = 3

Second, find the equation of the line using this following formula
y - y₁ = m(x - x₁)
plug in the numbers
y - 2 = 3(x - 1)
y - 2 = 3x - 3
y = 3x - 3 + 2
y = 3x - 1

The answer is option C
