Answer:

The correct option is B.

Step-by-step explanation:

It is given that the ordered pairs below represent a linear relation between x and y. (-3,0), (-2,4), (-1,8), (0,12), (1,16), (2,20).

At y-intercept the value of x is 0. From the given points we can say that the y-intercept of the function is (0,12).

If a line passing through the two points, then the slope of the function is

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

The slope of the function is

$m=\frac{4-0}{-2-(-3)}=\frac{4}{1}=4$

Therefore the slope of the line represented by this table is 4 and the y-intercept is 12. Option B is correct.
