    Answer:

    c,5y-4x=2

    Step-by-step explanation:

    y=mx+b

    y=4/5x+2/5

    so m=4/5, and y intercept x=0 so y=2/5

    Answer:

    C

    Step-by-step explanation:

    The equation of a line in slope- intercept form is

    y = mx + c ( m is the slope and c the y- intercept )

    Here m = \frac{4}{5} and c = \frac{2}{5} , then

    y = \frac{4}{5} x + \frac{2}{5} ( multiply through by 5 to clear the fractions )

    5y = 4x + 2 ( subtract 4x from both sides )

    5y – 4x = 2 → C
