Question

Which linear equation is represented in the graph? y = 3x – 1 y = x – 1 y = 2x – 1 y = x + 1

Answer 1

Answer:

y = 2x – 1

Step-by-step explanation:

The graph is a line then it’s equation has this form y = ax + b where a the slope and the y-intercept

the y-intercept b = -1 cause the line intersects the y-axis at the point (0 , -1)

$a=\frac{3-(1)}{2-0}=\frac{2}{2}=1$

Finally,

y = ax + b

  = 2x - 1
