Answer: 1
Step-by-step explanation: In algebra, we use the word slope to describe how steep a line is and slope can be found using the ratio rise over run between any two points that are on that line.
It's important to understand that rise over run is the same thing as slope so the slope of the line would be 2/2.
Notice however that 2/2 is not in lowest terms so we need to divide the numerator and the denominator by the greatest common factor of 2 and 2 which is 1 to get 1. So the slope of the line is 1.
