1. The slope is negative as the values on the y-axis are decreasing from the left to the right.

2. We need two points to calculate the slope. From the graph we can take the points (0,3) and (6,0). Using

the slope formula, we have:


m=(y2-y1)/(x2-x1)=(0-3)/(6-0)=(-3)/(6)=(-1)/(2)

So, the slope would be m=-1/2

3. The y intercept is equal to 3. We can identify it as it is the y-coordinate of the point where the line intersects the y-axis.
