    1 is C

    2 is A

    Slope intercept form is always y=mx+b (m and b are just there to hold places for numbers or fractions, the x is an x)

    just remember that your goal in doing these is to get the Y by itself on the left, so it looks like y=... then do proper math to arrange the last part to have the X first. That's all.

    For slope intercept form the equation must by written as y = mx + b. Where m is the slope and b is the x=intercept.

    1) 6x + 4y = 8

    4y = -6x +8

    y = (-6/4)x +2

    y= (-3/2)x +2

    The answer is C

    2) 4y = 3

    y = 3/4

    The answer is A

    This is a horizontal line that crosses the y axis and does not intercept the x axis. There is no slope or xintercept.

    slope intercept form is y = mx + b, so for the first one, you'd get the y part by itself by subtracting 6x from both sides, yielding: 4y = -6x + 8. Then divide everything by 4 and you get y = -(6/4)x + (8/4), which obviously reduces to y = -3/2x + 2 or answer C

    For the second one the answer is: A and I'll let you follow the instructions from above to show how that one is done

    Man that was sooo fun! Any more questions?

    I hope this helped!

    1.6x+4y=8

    4y=8-6x

    4y/4=8/4-6/4x

    y=-3/2x+2 c ans.

    2. 4y=3

    4y/4=3/4

    y=3/4 a ans.

    6x + 4y = 8

    6x + 4y - 6x = - 6x + 8

    4y = - 6x + 8

    4y/4 = - 6x / 4 + 8 / 4

    y = - 6x / 4 + 8 / 4

    y = - 3/2x + 2

    - - - - - -

    4y = 3

    4y/4 = 3/4

    y = 3/4
