Answer:
A
Explanation:
Slope = change in y/change in x
Choose any two points that are on the line, find the difference between the y and the difference between the x, and set as a fraction.
In this case, we can use (0,0) and (1,1) since both points are on the line.
Difference in y: 1 - 0 = 1
Difference in x: 1 - 0 = 1
Write as a fraction: 1/1
Simplify: 1
