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
