Question

8x+y=6?find y would it be -2?

Answer 1

No. you will get y in terms of x:

\(8x + y =6\)\[\implies y =-8x + 6\]

Answer 2

So that is the 'slope intercept' form of your line.

Answer 3

y=-8x+6?

Answer 4

Correct.

Answer 5

I just subtracted 8x from both sides:

8x + y = 6
-8x - 8x
===========
0x + y = 6 - 8x

\[\implies y = -8x + 6\]

Answer 6

OOOH So because you couldnt get a answer you rewrote it?

Answer 7

What?

Answer 8

I did get the answer. I just showed you another way to write it.

Answer 9

Oh

Answer 10

and the slope of the line?

Answer 11

The slope is the coefficient on the x variable. (The number in front of the x after you have solved for y).

Answer 12

So in this case, what is the number in front of the x?

Answer 13

8

Answer 14

-8 actually.

Answer 15

So negative 8 is the slope of the line.

Answer 16

:O TY!
