a
Explanation:
the x- intercept is the value of x on the x- axis where the line crosses.
The y- coordinate of any point on the x- axis is 0
substitute y = 0 into the equation and solve for x
y = 3x - 6 ← substitute y = 0
0 = 3x - 6 ( add 6 to both sides )
6 = 3x ( divide both sides by 3 )
=
x , that is
2 = x
the x- intercept is then x = 2 or (2, 0 ) in coordinate form
