B. Parallel to y=3x-5 and y-intercept =8 

C. Parallel to y=5 and y-inter=-3?

Each one is a different question or line which is why I added spaces between then please help I've been trying for days and I can't get it right help please

    The slope-intercept form of an equation of a line is y = mx + b

    where m is the slope and b is the y-intercept.

    A. m = 4 and b = -3

    Put those values into the slope-intercept form:

    y = 4x - 3

    ---

    B. Parallel to y = 3x - 5 and y-intercept = 8

    Parallel lines have the same slope. y = 3x + 5 has slope 3, so that's the slope we want for the desired line (m = 3). The y-intercept is 8 (b = 8).

    y = 3x + 8

    ---

    C. Parallel to y=5 and y-inter=-3?

    y = 5 is a horizontal line, and horizontal lines have slope 0 (m = 0). The horizontal line with y-intercept -3 has equation y = -3 . [slope m = 0, y-intercept -3 (b = -3)]
