well you want it to land on 5 or 6

so thats 2/6

6 divided by 2 is three

2 divided by 2 is 1

so, 1/3

Answer:

$y+2=-\frac{3}{2}(x-2)$

Step-by-step explanation:

Given:

Two points on a line are given as:

(0, 1) and (2, -2)

We know that the slope of a line passing through points $(x_1,y_1)\ and\ (x_2,y_2)$ is given as:

$m=\frac{y_2-y_1}{x_2-x_1}$

Plug in $x_1=0,y_1=1,x_2=2,y_2=-2$ . This gives,

$m=\frac{-2-1}{2-0}\\\\m=\frac{-3}{2}=-\frac{3}{2}$

The equation of a line with slope 'm' and points $(x_1,y_1)\ and\ (x_2,y_2)$ is given as:

$y-y_1=m(x-x_1)\\\\or\\\\y-y_2=m(x-x_2)$

Now, on plugging in the second point $(x_2,y_2)=(2,-2)$ we get:

$y-(-2)=-\frac{3}{2}(x-2)\\\\y+2=-\frac{3}{2}(x-2)$

Therefore, the first option is correct which is given as:

$y+2=-\frac{3}{2}(x-2)$

In the Changing Dimensions of 3D Figures

den301095 [7]

Answer:factor of 9

Step-by-step explanation:

Given

prism were changed by a scale factor of 3

Suppose prism is rectangular in shape

So surface are is $S.A.=2(lw+wb+lb)$

Where l=length

w=width

b=breadth

So new length,breadth and width is

$l'=3l$

$w'=3w$

$b'=3b$

$S.A.=2(3\times 3lw+3\times 3wb+3\times 3lb)$

$S.A.=2\times 3^2(lw+wb+lb)$

$S.A.=3^2\times 2(lw+wb+lb)$

So new surface area would change by a factor of 9
