You can put this solution on YOUR website!
It appears that y increases one as x increases one.
So the slope should be one.
It also looks like the y-intercept is one.
If so, the equation is y=x+1

By looking at the line, it looks like: y+=+%282%2F3%29x+%2B+1
Pick Two Points: (0,1) and (3,3)
Slope(M) = (y2 - y1)/(x2 - x1) = (3 - 1)/(3 - 0) = 2/3
Y-intercept: (0,1)
Use slope-intercept form:
y+=+mx+%2B+b where m is the slope and b is the y-intercept
y+=+%282%2F3%29x+%2B+1
