<u>Answer-</u>
<em>Option A</em><em> models the equation correctly.</em>
<u>Solution-</u>
The given equation is,





Comparing it with the general slope-intercept form of straight line,

Here,
m = slope = -2
y-intercept = 4
As the slope is negative in this case, so option B and option D are incorrect.
Now, calculating the x intercept,




So the x intercept is 2.
As in the option A, the y-intercept appears to 4 and x-intercept appears to be its half i.e 2. So option A is the correct graph.
