ANSWER

EXPLANATION
We want to find the equation of the straight line given on the graph.
The general form of a linear equation is given as:

where m = slope; b = y-intercept
To find the slope, we apply the formula for slope:

where (x1, y1) and (x2, y2) are two points on the line
Let us pick (1,2) and (4,4)
Therefore, the slope is:

To find the equation, we now apply the point-slope formula:

Therefore, we have that the equation of the line is:

That is the equation of the line.

The answer is 2 11/12 because you do 3 1/3 + -2 1/4 which gets you 1 1/2. Then you need to add 1 5/6 to the 1 5/6 to get your answer. So when you add up your answer you get 2 11/12. Hope this helps.
