Answer:</h2>

<h2>
Step-by-step explanation:</h2>
From the given graph, we can know two points:

Using the slope intercept form of the equation of a line, we get:

Where the slope is
and the y-intercept is 
From mathematics, we know that a system of two linear equations has no solution if and only if the two equations have the same slope, but not the same y-intercept. So, from the options, the second equation is:

And the slope intercept form of this equation is:

So the slope is
and the y-intercept is
, the systems formed by these two equations has no solution.
