Determine the slope and y-intercept for the line that passes through the points (5, 5) and (−5, 1). Show your work.

I found the slope its 2/5, but i don't know how to find the y-intercept. Can someone explain how to find the y-intercept please?

  1. You would graph the line with the found slope and plot it through the points and see where it crosses the axis.

    Better yet use a point ex) 5=(2/5)5 + b
    Following the form of y=mx+b

  2. Would the y-intercept be 3?

  3. since the y-intercept is the value of b when the equation is in the form
    y = mx + b

    from CodyJinks' line
    5=(2/5)5 + b , all we need to do is find b
    5 = 2 + b
    b = 3
