Answer:
y-4=-2(x-2) and y=-2x+8
Step-by-step explanation:
y=-2x+8 is correct because the slope is correct and the y-intercept is 8 as stated
y-4=-2(x-2) is correct because it uses a point given in the correct way and the slope is also correct
2x+y=8 is also correct because it can be converted to slope intercept form as y=-2x+8

Answer:
it b
Step-by-step explanation:
Solve equation [1] for the variable x [1] x = 3y - 1
// Plug this in for variable x in equation [2] [2] 8y - 2•(3y-1) = 4
[2] 2y = 2
// Solve equation [2] for the variable y [2] 2y = 2
[2] y = 1
// By now we know this much : y = 1
x = 3y-1// Use the y value to solve for x x = 3(1)-1 = 2
