Find the slope of the line represented by the table of values. A.1/2 B.1 C.2 D.4

tia_tia [17]

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

$m=\frac{y_2-y_1}{x_2-x_1}$

Choose any two pair of coordinates from the given points.

Let the line is passing through (5,4) and (7,5).

$m=\frac{5-4}{7-5}$

$m=\frac{1}{2}$

Therefore the slope of line is $\frac{1}{2}$ and option A is correct.
