Final answer:
The equation of a line in point-slope form can be determined using the given slope and a point on the line. The correct equation of the line in this case is y + 1 = 3(x - 5).
Step-by-step explanation:
The equation of a line in point-slope form is given by the formula: y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line.
In this case, the equation of the line in point-slope form can be determined using the given slope of 3 and a point on the line. Let's assume the point on the line is (5, -1). Plugging in the values, we get: y - (-1) = 3(x - 5), which simplifies to y + 1 = 3(x - 5).
Therefore, the correct equation of the line in point-slope form is y + 1 = 3(x - 5), which corresponds to option B.
