Answer:
the slope of the line is negative
Step-by-step explanation:
starting on the left and moving downwards gives the slope a negatie correlation
Answer: (4,2) , (2,1), (-2,-1)
Step-by-step explanation:
1/2x is the slope right?
So all you have to do is take a piece of graph paper, (slope being Rise over Run), and go right by 2, and go up by one. You can also do it going into the negatives, such as going left 2 and going down by one.
For x = ay - bz:
Add bz to both sides:
ay = x + bz
Divide a on both sides:
y = (x + bz)/a
For xy + yz = 10:
Distribute y from the left side:
y * (x + z) = 10
Divide by x + z:
y = 10/(x + z)
For (ab - ac)/z = x:
Multiply by z on both sides:
ab - ac = xz
Take out a from the left side:
a * (b - c) = xz
Divide by b - c on both sides:
a = xz/(b - c)
