Answer:

Option (D)

Explanation:

Zero of any function is defined by the x-value of the function when y = 0.

Let the equation of the line given in the graph is,

y = mx + b

where m = slope of the line

b = y-intercept of the line

Slope of a line passing through
(x_1,y_1) and
(x_2,y_2) is defined by the formula,

m =
(y_2-y_1)/(x_2-x_1)

If the passes through (0, -3) and (-2, 0)

m =
(-3-0)/(0+2)

m =
-(3)/(2)

Fro the graph,

y-intercept 'b' = -3

Therefore, equation of the line is,


y=-(3)/(2)x-3

For y = 0,


0=-(3)/(2)x-3


(3)/(2)x=-3

x = -2

Therefore, option (D) will be the answer.
