Without graphing, identify the slope and the y-intercept for the
line associated with each equation or table of values
5x + 20y = 60

  • Graphing -

    A straight line of the form y=mx+c has slope m and y intercpet of c.

    So we need to rearrange the equation into this form

    20y=-5x+60

    so

    y=(-5x/20)+ 60/20

    y=-0.25x+3

    thus m=-0.25 and c=3
