    Answer: y=4x

    Step-by-step explanation:

    1. Let’s call:

    y: yellow pencils.

    x: blue pencils.

    2. You know that Shawna found out there are 4 yellow pencils for every blue pencil, therefore, you can make the following expression based on this information:

    y=4x

    3. Therefore, if there is 1 blue pencil, subtitute x=1 into the equation and you obtain:

    y=4(1)

    y=4 (There are 4 yellow pencils)

    4. If there are 2 blue pencils, then x=2 and:

    y=4(2)\\y=8 (There are 8 pencils)

    Answer:

    The equation for this situation is, y =4x

    Step-by-step explanation:

    Unit rate is defined as the rates are expressed as a quantity 1 such as 5 miles per hour or 4 meter per second.

    As per the given statement: Shawna found out there are 4 yellow pencils for every blue pencil.

    ⇒ for every blue pencil there are 4 yellow pencils.

    Unit rate per blue pencil(m) = 4 yellow pencils

    Let y represents the yellow pencils and x represents the blue pencils.

    The equation of line is given by;  y =mx

    where m is the slope or unit rate.

    Substitute the value m = 4, we get;

    y = 4x

    Therefore, the equation for this situation is, y =4x
