Question

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

X Y
-1 1
1 2
3 3
5 4
7 5

Answer 1

The actual answer is C

Explanation:

Answer 2

The correct option is A.

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=(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=(5-4)/(7-5)`

`m=(1)/(2)`

Therefore the slope of line is
`(1)/(2)` and option A is correct.
