Find the slope, if it exists
x+5y=10

  • algebra -

    to get the slope, we first transform this into slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.
    x + 5y = 10
    note that in slope-intercept form, y is the only term on the left side, and all other terms on the right side. thus,
    5y = -x + 10
    then also notice that the numerical coefficient of y (number before y) is 1. thus we divide both sides by 5 to get y alone:
    y = (-1/5)x + 2
    thus, m = slope = -1/5

    hope this helps~ :)
