Answer:
y = x-1
Step-by-step explanation:
First step is to find the slope
Take two points on the line (1,0) and (2,1)
m = (y2-y1)/(x2-x1)
= (1-0)/(2-1)
= 1/1
The slope is 1
The y intercept ( where it crosses the y axis is -1)
The slope intercept form of the line is
y = mx+b where m is the slope and b is the y intercept
y = 1x-1
y = x-1
