<h2>Answer: y = -1x + 2</h2>

Step-by-step explanation:

Points ( -3,5 )( 6,-4 )

You use the slope formula to find the slope.

<h3>Note: You'll need to learn the slope formula to make more sense of it, I suggest watching a video about it.</h3>

M = Y2 - Y1 over

      X2 - X1

Which is -4 - 5

               6 - -3 =         -9/9 = -1

The slope is -1

Now to find the y-intercept we use one of the x,y points ( I'll use 6,-4 )

And plug them in

-4 = -1(6) + b

-4 = -6 + b

+6   +6

2 = b

The equation will be y = -1x + 2

A structural steel fabricator cuts 25 pieces each 16.2 centimeters long from a 6.35-meter length
Daniel [21]

Answer: 2.2 meters

Step-by-step explanation:

The data is:

The initial piece is 6.35 meters long.

We cut 25 pieces of 16.2cm each, so in pieces only we have:

25*16.2cm = 405cm

1m = 100cm

Then: 405cm = (405/100) m = 4.05m

And each time that we cut a piece, we have 4mm of waste.

Then we have 25 times the 4mm of waste, this means that the total waste is:

4mm*25 = 100mm

and 1000mm = 1m

100mm = (100/1000) m = 0.1m

So the total amount that was cut is:

4.05m + 0.1m = 4.15m

The length in the channel iron will be: 6.35m - 4.15m = 2.2 meters
