the straight line the straight line the straight line is defined as the shortest distance between two points a straight line is just a line which joins two points without any curve in geometry a straight line is made by joining simple two points in other words you can say straight line eliminates the distance between two points in graph straight line can be represented as the above diagram shows that pq is a straight line and it is not a curve formula of straight line is stated by a linear equation and its general form is px qy c 0 here p,q are not both 0 now straight line equation is given by y mx+d where value of m is the given slope and the y-intercept is given by d for making a straight line you have to follow certain steps and the steps are know more about how to determine the infinite limit tutorcircle.com page no 1/4

first of all mark the first end point then secondly mark the second end point thirdly just connect the two end points the above steps are known as straight line straight line theorem can be described as if a line r intersects another line i.e s then the angle made by the line s above line r is the complementary angle mathematically the straight line through two different co ordinate points a1 b1 and a2 b2 is given by i b b1 b2 ­ b1 a2 ­ a1 · a ­ a1 where a1 and a2 are supposed to be distinct if suppose the two points are equal then the equation can be written as a a1 and it does not need a second point the above equation can also be written as b ­ b1 b2 b1 a2 ­ a1 · a ­ a1 or it can be written as a2 ­ a1·b ­ b1 b2 ­ b1·a ­ a1 whereas the easiest formula for the straight line to remember is this b ­ b1 b2 ­ b1 a ­ a1 a2 ­ a1 learn more perfect matching bipartite graph tutorcircle.com page no 2/4

which is the simplest formula of all the above used intercept-intercept formula of the straight line suppose any straight line meet at x-axis at p 0 and at y-axis at 0 q then it is defined by the equation x/a y/b 1 and it can also can be written as ax by ab point-slope formula of the straight line the equation of a straight line through point p q with a given slope of m is y mx a b or y b mx a parametric equation of the straight line is given by suppose a straight line passes through a point s0 a b which is parallel to the vector u n m is given by x y p q t·n m where t is any real number it can also be written as in vector form s s0 t · n where r x y now let s deal with the topic bar graph tutorcircle.com page no 3/4 page no 2/3
