Question

if a straight line passing through the points p(X1,y1),Q(X2,y2) , making an angle of teta with positive x axis then find the slope of the straight line​

Answer 1

ANSWER:-

GIVEN:

__________

The line is passing through the points P(X1,Y1) and Q(X2,Y2).

The measure of angle is theta

SOLUTION:

_______________

The slope of the line is tan theta or
