1. Refer to the equation 2x - 4y = 12

Masja [62]

The coordinate pair can be obtained from the given equation by

rearranging the equation to make <em>y</em> the subject of the equation

The table of values obtained from the given equation is presented as follows;

$\begin{array}{|c|cr|} \mathbf{x}&&\mathbf{y}\\0&&-3\\1&&-2.5\\2&&-2\\3&&-1.5\\4&&-1\end{array}\right]$

The graph showing the points in the above table is attached

Reason:

The given equation is presented as follows;

2·x - 4·y = 12

(a) The values are found by making either <em>x</em>, or <em>y</em> the subject of the

formula, and inputting values as follows;

2·x - 4·y = 12

= 4·y

4·y = 2·x - 12

$\dfrac{4\cdot y}{4} = \dfrac{2 \cdot x - 12}{4}$

The rearranged equation is therefore

$y = \dfrac{x }{2} - 3$

Plugging in values of <em>x</em>, (0, 1, 2, 3) to find the corresponding y-values gives;

x = 0

$y = \dfrac{0 }{2} - 3 = -3$

x = 1

$y = \dfrac{1 }{2} - 3 = -2 \dfrac{1 }{2}$

x = 2

$y = \dfrac{2 }{2} - 3 = -2$

x = 3

$y = \dfrac{3}{2} - 3 = -\dfrac{3}{2} = -1.5$

x = 4

$y = \dfrac{4}{2} - 3 = -1$

<u>The table of values</u> is therefore;

$\begin{array}{|c|cr|} \mathbf{x}&&\mathbf{y}\\0&&-3\\1&&-2.5\\2&&-2\\3&&-1.5\\4&&-1\end{array}\right]$

The <u>graph of the points</u> can be <u>plotted</u> using MS Excel as presented here

How are we supposed to do this?

make a plotting graph and use the x and y axis and make little point :) hope this helps

Step-by-step explanation:

the vertex is the point, where the parabola turns around. it is (depending on its orientation, if it is opening upwards or downwards) the maximum or the minimum of the curve.

so, as we can see on the grid, that point is x = -3, y = +1 = (-3, 1).

so, B is correct
