Please help dont answer if u dont know it

c

Step-by-step explanation:

The answer is c. The formula for slope is change in y/change in x. To find the slope of this line, let's randomly choose 2 points from this graph.  To keep this simple let's just choose the points (1, 1) and (2, 3). Let's subtract the y coordinate 1 from the y coordinate 3 to find the change in y. You will get 2 as your change in y.  Now, lets subtract the x coordinate 1 from the x coordinate 2 and you should get 1 as your change in x.  Now, all that's left to do is put it together 2 (change in y)/1 (change in x) is 2/1 which can be simplified to 2. So the answer is c. Hope this helps!
