Answer:

I think what you are asking for is an example.

Step-by-step explanation:

Standard form equation

8x-4y = 20

1. move 8x to the other side

-4y=20-8x

2. divide both sides by -4

\frac{-4y}{-4} = \frac{20-8x}{-4}

3. Solve for this...

y=2x-5

1) The graph shows y as a function of x Suppose a point is added to this graph. Which choice gives a point that preserves the fu
barxatty [35]
<h3>Answer:  B)  (0,9)</h3>

==========================================================

Explanation:

The points on the given graph are:

  • (-7,4)
  • (-3,-3)
  • (2,9)
  • (3,-8)
  • (5,7)
  • (9,3)

Notice that the <em>slightly</em> darker grid lines indicate 5 on either x or y axis. This helps visually spot where the points are fairly quickly. Though admittedly, it would be better if your teacher provided numbers on the x and y scales.

Now if we were to add something like point A(5,5) to the graph, then this function would cease to be a function. This is because the points (5,7) and (5,5) fail the vertical line test. The input x = 5 leads to the outputs y = 5 and y = 7 at the same time. A function is only possible if any x input leads to exactly one y output only.

So this is why we eliminate choice A from the possible answer pool.

Choice C is a similar story. The two points (9,3) and (9,-1) fail the vertical line test this time, i.e. the input x = 9 has multiple outputs y = 3 and y = -1 simultaneously. We rule out choice C.

Choice D is also ruled out because of (2,-4) and (2,9) failing the vertical line test.

We're left with choice B. Luckily, adding the point (0,9) to the mix does not break the function. The input x = 0 wasn't part of the original function.

-------------------

In short, we eliminate choices A,C and D because they fail the vertical line test. Choice B does not fail the vertical line test so it's the final answer.

Answer:

-2/3

Step-by-step explanation:

The slope is the coefficient of x: -2/3.
