By calculations, line l has a slope of 1 and line k has a slope of 2
How to determine the slopes of the lines
From the question, we have the following parameters that can be used in our computation:
The graph
The slope of a line is calculated using
Slope = Rise/Run
Where
RIse = Change in y
Run =Change in x
Using the above as a guide, we have the following:
Line l = (2 - 1)/(2 - 1)
Line l = 1
Line k = (4 - 2)/(2 - 1)
Line k = 2
Hence, line l has a slope of 1 and line k has a slope of 2
