Hi there! The correct answer is C.
The standard form of a line is y = ax + b
a represents the slope
b represents the y-intercept.
The slope is 0, so a = 0, filling in we get:
ax --> 0 * x = 0
The y-intercept is -2/3, so b = -2/3
Now we get our answer:
y = 0 + - 2 / 3 = - 2 / 3
Answer C. is correct.
