Answer:

D

Explanation:

the x- intercept is the point where the line crosses the x- axis.

any point on the x- axis has a y- coordinate of zero.

let y = 0 in the equation and solve for x , that is

4x + 2 = 0 ( subtract 2 from both sides )

4x = - 2 ( divide both sides by 4 )

x =
(-2)/(4) = -
(1)/(2) ← x- intercept

coordinates of x- intercept = (-
(1)/(2), 0 )
