Answer:
D.) -2/7
Explanation:
First things first, we can automatically cross out any positive answer as this line has a negative slope. If you graph y = -x, you can see that the graph goes from the second quadrant to the fourth one. (If you graph y = x, it does the opposite, going through the third and first quadrants)
So you can totally get rid of B and C.
Now we can use point slope form to find the slope. Using the point slope form formula, (y2-y1)/(x2-x1) = m
Where m is the slope of the line and ( x1, y1 ) is one given point and (x2, y2) is another given point. So let's start
(y2-y1)/(x2-x1) = m
(1-3) / (3- (-4)) = m
(-2)/7 = m
so your slope would be -2/7!
