Explanation:
The point-slope form of an equation of a line:

m - slope
(x₁, y₁) - point on a line
We have the slope m = -5, and the point (2, 6).
Substitute:

The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
Convert:
use the distributive property a(b + c) = ab + ac

add 6 to both sides

The standard form of an equation of a line:

Convert:
add 5x to both sides
