    The slope is 2/5

    Step-by-step explanation:

    Slope-Intercept form: y = mx + b

    m = slope b = y-int

    To find the slope, you must rewrite the equation in slope-intercept form by using inverse operations to isolate the y.

    1) Subtract 2x from both sides of the equation:

    2x - 2x - 5y = 9 - 2x Result: - 5y = - 2x + 9; Notice the numbers are rearranged to keep the slope-intercept form. As long as you keep the correct sign, you can rearrange them.

    2) Divide both sides by - 5:

    - 5y / - 5 = - 2x / - 5 + 9 / - 5 Result: y = 2/5x - 9/5

    b = - 9/5

    m (slope) = 2/5
