All equations are in slope intercept form. Since the slope is decreaseing as x increases, the slope is negative. Another thing is its y intercept is positive so therefore this leads to the conclusion
The answer is D because every time the graph is facing the left (meaning the line is more up on the left) it means the slope (number besides the x) is negative, and if it is to the right (the line is more up on the right) the slope (number besides the x) is positive. And the y intercept (that is the number that it’s alone) in this case is positive 4 because it is crossing the y axis approximately at 4. It was a big explanation but it will help you get it. Hope it helps!!!
