Answer:
Lets calculate the slope of the line 'l'
Slope is rise over run of a line, so we will see how much the y of the line changes by changing x by 1
So, basically we will select a point on the line and see how much the y-value increases for the point rightward to our point
we see that the y increased by 1 and hence, its slope is 1
Now, the slope of line 'k'
again, we will select a point and go one point to the right
here, we see that the y increases by 2
therefore the slope of line 'k' is 2
