The equation of blue line is y= 1/2x+2.
<h3>What is equation of line?</h3>
The standard form of equation of a line is ax + by + c = 0. Here a, b, are the coefficients, x, y are the variables, and c is the constant term. It is an equation of degree one, with variables x and y.
As from the graph we can see that the y - intercept is 2.
Also the function crosses y - axis at 2.
So, slope of the function is 1/2.
Now using
slope= rise/ run
1/2= y/x
y= 1/2x
Now, slope intercept form: y = mx + b
y= 1/2x+2
