#1,

Answer is 4x + -3y = 8

#2,

8-4(x-y)=-6x+6
8 - 4x + 4y = -6x + 6
-4x +4y = -6x -2
2x + 4y = -2

Answer is D.

#3,

x-intercept can be found when y = 0

8x - (1/3)y = 16
8x - (1/3)(0) = 16
8x = 16
x = 2

Your answer is 2

#4,

2x + 5y = 10
5y = -2x + 10
y = (-2/5)x + 2

The y-intercept is 2
The slope is negative.

Only line b fits this equation.
