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

Answer 1

I believe it is B when you plug in the numbers

Answer 2

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 =
`(y_(2)-y_(1))/(x_(2)-x_(1))`
m =
`(-1-2)/(0-1)`
m =
`(-3)/(-1)`
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
