Answer:  $\textsf{y = -2/5x}$

-------------------------------------------------------------------------------------------------------------

Given:  $\textsf{Passes through (5, -2) and slope of -2/5}$

Find:  $\textsf{The equation that follows the details provided}$

Solution: We first need to plug into the point-slope form and after simplifying, distributing, and solving for y we will complete our equation.

Plug in the values

• $\textsf{y - y}_1\textsf{ = m(x - x}_1\textsf{)}$

• $\textsf{y - (-2) = -2/5(x - 5)}$

Distribute and simplify

• $\textsf{y + 2 = -2/5(x - 5)}$

• $\textsf{y + 2 = (-2/5 * x) + (-2/5 * (-5))}$

• $\textsf{y + 2 = -2/5x + 2}$

Subtract 2 from both sides

• $\textsf{y + 2 - 2 = -2/5x + 2 - 2}$

• $\textsf{y = -2/5x + 2 - 2}$

• $\textsf{y = -2/5x}$

Therefore, the final equation that follows the information that was provided is y = -2/5x.
