Find the slope of the line on the graph. Write your answer as a fraction or a whole number, not as a mixed number or decimal.

The slope of the line on the graph is 1

Step-by-step explanation:

When finding slope, you can follow the listed formula :

Now what does this mean? Rise is talking about the length for the y axis, while run is talking about the length for the x axis.

So what you want to do is find two points on the line that touch an actual number and doesn't stop in the middle of a square. In this case, I see (0,4) and (3,1).

So now you want to see how many squares make up the distance for the two points, so move down and you count 3 squares to equal to (0,1), now try to find a way to get to (3,1). Move three squares to the right.

Now, since you moved 3 squares down on the y axis, you replace that with rise on the fraction.

Now since you moved 3 squares right on the x axis, you replace that with run on the fraction.

Now divide :

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
