Question

hello mate

what is a point slope form

Answer 1

Here is your answer-

 The equation of a straight line in the form y − y1 = m(x − x1) where m is the slope of the line and (x1, y1) are the coordinates of a given point on the line — compare slope-intercept form.

m is slope.

• The slope of X-axis and of any line parallel to X-axis is zero.

• The slope of y axis and of any line parallel to y-axis cannot be determined.

When angle is given and to find slope

Formula :-
m = tan theta

You can understand by the pictures..

Hope it helps you. !
