Math Linear function help?

posted by .

How do you write an equation of a line in slope intercept form if two points are given? Ex. Say you were given the points (0,6) and (4,3)? What would you do?

  • Math Linear function help? -

    The slope of the line is
    m = (y2-y1)/(x2-x1)
    =(3-6)/(4-0) = -3/4

    When x = 0, y = 6, so the y-intercept is 6.

    y = (-3/4)x + 6 is the equation you want.
