Answer:

y= 2x+1

Step-by-step explanation:

Points:

(0,1) and (1,3)

Form of the line:

y=mx+b, m- the slope, b- y-intercept

Finding the slope:

m= (y2-y1)/(x2-x1)
m=(3-1)/(1-0)= 2/1= 2

Line is now:

y= 2x+b

Using one of the given points to find out the value of b:

1=2*0+b
b=1

So the equation for the line is:

y= 2x+1
