What is the equation of the line that contains the following points? (-2,8) (-1,4) (0,0) (1,-4) (2,-8) ?

The equation is y = -4x

Step-by-step explanation:

In order to find the equation of the line, we need to take two points and use the slope formula. For the purpose of this, we will use (1, -4) and (0, 0)

m(slope) = (y2 - y1)/(x2 - x1)

m = (-4 - 0)/(1 - 0)

m = -4/1

m = -4

Now that we have the slope, use that and either point in point-slope form and solve for y.

y - y1 = m(x - x1)

y - 0 = -4(x - 0)

y = -4x

26?

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
