Question 65222
An equation written in slope-intercept form will look like
y=slope times x + y intercept
This is normally abbreviated to
y=mx + b (some people use c here ) where the m is the slope of the line and b is the y intercept
In your example you are told the slope (m=1) and the y intercept  (0,2) 
So your equation is 
y = 1x + 2

y = x + 2
