Answer:
If the graph is rising from left to right, like climbing a hill, the slope is positive (on a graph, you could count up y units divided by right x units). If it is going down from left to right (like sliding down a hill), the slope is negative (on a graph you have to count down y units and right x units). Does this help?
Answer:
Step 1:
Plot and label 2 points on the line, anywhere on the line of course. Remember that the slope of a line never changes, so you can choose whatever 2 points on the graph you want and you will always get the same slope.
Step 2:
Calculate the rise and run (It is easier to draw it on the graph in my opinion)
Step 3:
Use the slope formula.
As an example, lets say the slop is 2/4, which you can simplify it down to 1/2 to make it easier of course.
Hope this helps!
