1. the x-intercept of a line is -3. the y-intercept of the line is 6. what is the slope of the line?

2. what is the equation in slope-intercept form of the line described in Exercise 1?

  • math -

    1. The x-intercept coordinates are (x1,y1) = (-3,0).
    The y-intercept coordinates are
    (x2,y2) = (0,6).
    The slope is
    m = (y2-y1)/(x2-x1)

    Do the calculations and see what you get.

    2. After you have solved for m, write the equation on the form
    y = m x + b
    You can use that equation with either (x1,y1) or (x2,y2) to figure out what b is.
