<h2>Explanation:</h2>Looking at the graph we realize that the y-intercept is given by:
The Slope-intercept form of the equation of a line is given by:
So, our equation becomes:
So the only option that matches a negative y-intercept is C. Let's see that the slope . Look at the y-intercept, if you increase x by 3 units, then y increases by 2 units and goes from
to
