Answer:
y = 2x -1
Step-by-step explanation:
y = mx + b
On the y-axis which is the vertical line, it touches the line is on -1.
Therefore, -1 is the y-intercept which is b.
y = mx - 1
Now the slope since it goes up 2 and right one to reach a point again the slope is 2/1 which basically just 2.
Now y = 2x - 1
