Recall the point-slope form of a linear equation, which is given by the formula: \[y - y_1 = m(x - x_1)\] where \(m\) is the slope and \((x_1, y_1)\) is a point on the line.
Identify the given slope \(m = \frac{1}{3}\) and the given point \((-2, 4)\). Here, \(x_1 = -2\) and \(y_1 = 4\).
Substitute the slope and the coordinates of the point into the point-slope formula: \[y - 4 = \frac{1}{3}(x - (-2))\].
Simplify the expression inside the parentheses by changing the subtraction of a negative number to addition: \[y - 4 = \frac{1}{3}(x + 2)\].
This is the equation in point-slope form representing the line with slope \(\frac{1}{3}\) passing through the point \((-2, 4)\).
