    Equation of a Line

    - Equations that Describe a Line

    Slope
    Choice B

    Step 1: Rearrange the equation to solve for y

    2x+5y=92x+5y=9
    5y=−2x+95y=-2x+9
    y=−{2}{5}x+{9}{5}y=-\frac\{2\}\{5\}x+\frac\{9\}\{5\}

    Step 2: find the slope m

    As we know that

    y=mx+by=mx+b

    where m is the slope.

    ∴Slope=−{2}{5}\therefore Slope=-\frac\{2\}\{5\}
