-12x - 9 = -6y
-12x + 6y -9 = 0
-12x + 6y = 9 is the answer
The slope (m) of the line graphed is -4/2, because the line goes down 4 (-4) and over 2 (+2), which is change in y over change in x
m = -4/2 = -2
the y-intercept (b) of the line = -1, because the line crosses the vertical line at x=0 at y=-1
now for the equation:
y = mx + b
y = -2x + -1 = -2x - 1
f(x) = -2x-1
the last answer is correct
Answer:
y < 5/2x + 5
Step-by-step explanation:
slope goes up 5, then over 2 ( 5 on top, 2 on bottom --> 5/2)
y intercept is +5

Answer:
(x, y, z) = (x, x+2, 3x+1)
Step-by-step explanation:
We can add twice the second equation to the first to get ...
[eq4] -3x +0y +z = 1
Adding the first and second equations gives ...
[eq5] -x +y +0z = 2
Solving [eq4] for z gives ...
z = 3x +1
Solving [eq5] for y gives ...
y = x +2
Then the solution triple is (x, y, z) = (x, x+2, 3x+1).
