    Equation of a Line

    - Equations that Describe a Line

    Slope
    Choice G

    We have to find the slope of the following equation

    x+5y=9x+5y=9
    5y=−x+95y=-x+9
    y=−{1}{5}x+{9}{5}.............(1)y=-\frac\{1\}\{5\}x+\frac\{9\}\{5\}.............(1)

    We know that the equation of slope is

    y=mx+c................(2)y=mx+c................(2)

    where,

    m={a}{b}m=\frac\{a\}\{b\}

    So comparing equation (1) with (2), we have

    slope=m=−{1}{5}slope=m=-\frac\{1\}\{5\}
