Final answer:
A line with a slope of "-5/3" points downwards when viewed from left to right, due to the negative value indicating a decline in the line's direction.
Step-by-step explanation:
When addressing the question of which direction a line with a slope of "-5/3" would point when viewed from left to right, we must recall that the slope of a line indicates its steepness and direction. A negative slope means the line is falling or going downward as it moves from left to right. Therefore, given that "-5/3" is a negative number, the line would point downwards.
A line with a slope of -5/3 would point diagonally downwards from left to right in the coordinate system. This means that as you move from the left side to the right side, the line would be going downwards. So the answer is: B. Downwards.
