Answer:
Positive.
Step-by-step explanation:
As you go along the x axis and the values of x increase, the values of y also increase. For example, at x = 2 the value of y is 1, and at x = 8 the value of y is 4. This means that the values of y are always increasing as you go up the x axis, so the slope is positive.
You can also tell this from the shape - the line, if read from left to right, is going up, so is positive.
