Final answer:
The equation y = 4/3 represents a horizontal line with a y-intercept of 4/3 and a slope of 0, which is not represented in the provided options.
Step-by-step explanation:
To find the y-intercept and slope of the line represented by the equation y = 4/3, we observe that this equation is a horizontal line. In the slope-intercept form of a linear equation, which is y = mx + b, the m represents the slope and the b represents the y-intercept. However, since there is no x term in the equation y = 4/3, this means that the slope is 0 because the line is horizontal and does not rise or fall regardless of the value of x. Therefore, the correct answer is that the y-intercept is 4/3 and the slope is 0, which is not listed among the options provided. This suggests there might be an error in the given options.
