Answer:
The correct option is A.
Step-by-step explanation:
From the given table it is noticed that the line is passing through the points (-1,1), (1,2), (3,3), (5,4) and (7,5).
Slope of a line is calculated as
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Choose any two pair of coordinates from the given points.
Let the line is passing through (5,4) and (7,5).
[tex]m=\frac{5-4}{7-5}[/tex]
[tex]m=\frac{1}{2}[/tex]
Therefore the slope of line is [tex]\frac{1}{2}[/tex] and option A is correct.
