plz, answer quickly !!!!!!!!!!!!!!!!!!!

Answer:
y=2x-1
Step-by-step explanation:
Slope intercept form is y=mx+b.
To start, we know that the y-intercept, b, is -1 because we can see where the line crosses the y-axis. Next, we can calculate the slope by counting how many steps up/down and to the side the line goes when looking at points it crosses through.
We know that this line crosses through (0, -1) and (1,1) so we would count "up 2 over 1"
2/1
2
m=2
Now we can write our equation.
y=2x-1
HTH :)
