una recta pasa por los puntos A(1,2) y el punto B ( 4,5) determinar cual es el valor de la pendiente de la recta.

  • Pendiente

    m = (5-2)/(4-1) = 3/3 = 1

    Ecuación

    y - 2 = x - 1

    y = x + 1

  • How do I find the equation for the straight line with two points A (1 ; 2) and B (4 ; 5) ?

    The typical equation of a line is: y = mx + b → where m: slope and where b: y-intercept

    To calculate m

    m = (yB - yA) / (xB - xA) = (5 - 2) / (4 - 1) = 3/3 = 1

    The equation of the line becomes: y = x + b

    To calculate b

    The line passes through A, so the coordinates of this point must verify the equation of the line.

    y = x + b

    b = y - x → you substitute x and y by the coordinates of the point A (1 ; 2)

    b = 2 - 1 = 1

    → The equation of the line is: y = x + 1

  • ¿Porque nosotros tenemos que hacer eso si te lo dieron a vos?
