Answer:
A)
Step-by-step explanation:
Hi there!
The given equations are written in point-slope form: where <em>m</em> is the slope of the line and
is a point that falls on the line
Notice how the line is travelling infinitely down as x increases. This means that the slope is negative.
Therefore, the equation of the line is either A or B.
Now, let's look at A:
This equation suggests that the point (4,-7) falls on the line, which it does.
Therefore, the equation of the graph is .
I hope this helps!
