Hello!!
We can look at the points given on the graph. (-1, -7), (0, -1), and (1, 5).
Now, we can the formula, where m stands for slope: m = (y2 - y1)/(x2 - x1). NOTE: (the 1's and 2's are supposed to be subscripts.
Pick two of the three given points, I'll use (0, -1) and (1, 5).
m = (5 - (-1))/(1 - 0) = 6/1 = 6
The slope of the line on the graph is 6.
Hope this helps!! Let me know if you have ANY questions.
