A 3 metre long piece of ribbon is cut into

Gnoma [55]

Step-by-step explanation:

3 meters = 300 cm

anyway, the ratio tells us that the whole ribbon can be seen as the combination of 3 + 2 = 5 equally long parts.

one such part is then

3 m / 5 = 0.6 m or 60 cm

the shorter piece is 2 of these parts long :

2 × 0.6 = 1.2 m or 120 cm

Which equation represents the line that passes through the points (-4,4) and (8,-2)?

Helen [10]

Answer:

$y=-\frac{1}{2} x +2$

Step-by-step explanation:

$m=\frac{y2-y1}{x2-x1} = \frac{-2-4}{8-(-4)} =\frac{-6}{12} = -\frac{1}{2}$

So for a movement along the x-axis left to right by 2 the y-axis drops by 1

This the equation at this point is =

$y=-\frac{1}{2} x+c$

-

Pick any of the two points (x,y) . let's choose ( 8 , -2 )

$y2=-\frac{1}{2} x2+c \\\\..\\\\-2=(-\frac{1}{2} )(8)+c\\-2=-4+c\\\\..\\\\c=2$

SO ..

$y=-\frac{1}{2} x+2$
