To write an equation in point-slope form, we use the formula:
\[ y - y_1 = m(x - x_1) \]
where \( (x_1, y_1) \) is the given point and \( m \) is the slope.
Given the point \( (4, -6) \) and the slope \( m = \frac{3}{5} \), we can plug these values into the formula:
\[ y - (-6) = \frac{3}{5}(x - 4) \]
Simplifying this gives:
\[ y + 6 = \frac{3}{5}(x - 4) \]
So the equation in point-slope form is:
\[ y + 6 = \frac{3}{5}(x - 4) \]
