Answer 1

Do you know how to solve the equation for y?

Answer 2

If you solve the equation for y, you will have the slope-intercept form which is:
\(y = mx + b\)
Then the slope is simply m, the number multiplying x.

Answer 3

That just confused me >.<

Answer 4

Which part are you struggling with?

Answer 5

Here is a simple example.
What is the slope of the line with equation y = 3x + 5
Answer: 3
Since the equation in this example is already solved for y, the slope is the number that mutiplies x.

Answer 6

correct

Answer 7

If you have an equation of a line already solved for y, you can read the slope directly.

Answer 8

In your question, your given equation is not solved for y.
If you do solve the equation for y, then you'll be able to read the slope off the equation.

Answer 9

This is why I asked you at the top if you know how to solve the equation for y.
If you know, just do it.
If you don't know, just say so, and I'll guide you through it.

Answer 10

No i don't know. This is probably the worst part of the unit so far..
I understand about 10% of the crap i'm learning

Answer 11

Ok. Let's solve this equation for y.
We want y by itself on one side of the equation and everything else on the other side.

Answer 12

First, let's switch sides, so we have y on the left side.

\(-48 = 2x - 8y\)

\(2x - 8y = -48\)

Answer 13

2x is being added to -8y
We want to get rid of 2x from the left side, so we subtract 2x from both sides of the equation.

Answer 14

So take 2x out of 8y and -48?
