Unformatted text preview: THE TWO-POIN T FORMULA If a line passes through two given points (x1 , yl) and (x2 ,y2 ), then the EQUATION of the line can be determined using this one formula: This formula is identical to y—y1 = m(x —x1), y2—y1 Where the m is replaced with x2“x1 Example: Find the equation of the line passing through (2, —3) and (4 , 1). Solution: Let (x1,y1.) = (2, —3) and (x2,y2) = (4,1) y2—y1 y—y1= (x—xl) x2—x1 1——3 m —— —2 beco es y 3 4_2 (x ) y+3 2(x—2) y+3 2x—4 y 2x—7. ALTERNATIVELY the equation of the line can be determined by using two concepts already covered: yz—yi (i) Find the gradient by using m = . x2_x1 (ii) Determine the equation by using y —y1 = m(x —x 1). ...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
