It means expressing the linear equation in terms of two known quantities: one point on the line and its slope.
The general form of a line is y = ax + b, where a represents the slope and b be the y-intercept. If (m,n) is a point on the line, then n = am + b, or b = (n - am). Both a and (m,n) are assumed to be known or given. The point-slope form of the line becomes y = ax + (n - am). Then we re-arrange the equation to make it more recognizable as the point-slope form.
Either express the equation as (y-n) = a(x-m) or y = a(x-m) + n.
If you use the convention that slope is designated by the letter m, and the point that is on the line designated by (x1,y1); the point-slope form is y - y1 = m(x - x1)

Point-slope form is written as: y-y1=m(x-x1), where (x1, y1) is a point on the line and m is the slope (hence the name, point-slope form).
No line described, but here is the point slope form. Y - Y1 = m(X - X1) =============
The equation of the line will also depend on its slope which has not been given and so an answer is not possible.
Point-slope form is just another way to express a linear equation. It uses two (any two points that fall on the line) and the slope of the line (Therefore the name point-slope form).y2 - y1 = m(x2 - x1)...with m as the slope.
When it is a line through the origin.
