Final answer:

Using the point-slope form of the equation of a line, the equation for a line passing through the point (4, 1/3) with a slope of 3/4 is derived to be y = 3/4x - 8/3. However, none of the provided options match this equation, indicating a possible typo in the options.

Step-by-step explanation:

To find the equation of a line that passes through a specific point and has a given slope, we can use the point-slope form of the equation of a line, which is:



y - y1 = m(x - x1), where (x1, y1) is the point through which the line passes and m is the slope of the line.



Given the point (4, 1/3) and the slope 3/4, we can plug these values in to get the equation of the line:



y - 1/3 = 3/4(x - 4)



To find the equation in slope-intercept form, which is y = mx + b, we will simplify the above equation:



y - 1/3 = 3/4x - 3



Adding 1/3 to both sides gives us:



y = 3/4x - 3 + 1/3



Finding a common denominator and combining terms gives us:



y = 3/4x - 9/3 + 1/3



y = 3/4x - 8/3



Therefore, the equation that represents the line is:



y = 3/4x - 8/3



However, none of the options given in the student's question has this equation, there may be a typo in the options. The correct answer with the slope 3/4 and passing through the point (4, 1/3) is not listed.
