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)

β 13y agoPoint-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.
if a line has a slope of -2 and a point on the line has coordinates of (3, -5) write an equation for the line in point slope form

Write the equation in slope-intercept form of the line that has a slope of 2 and contains the point (1, 1).

You use point-slope form to find the equation of a line if you only have a point and a slope or if you are just given two point. Usually you will convert point-slope form to slope-intercept form to make it easier to use.

Point slope form of y-7=-3x identifies the line that pass through the slope of line (-2 -5) (7 -6).
Write the equation of a line in slope-intercept form that has a slope of -2 and passes through the point (2, -8).
You need either a point and the slope of the line or two points. Then you use the point slope form of the line or the slope intercept form to write the lines.A given point has an infinite number of lines going through it, that is why you need more information.
