Question

Question 2.2. Find the slope and y-intercept of each line.

y = x – 3

Answer 1

Do the same thing I told you.

This is the basic formula: y = mx + b

m = slope

slope = 1

b = -3

Answer 2

so when x is by its self its 1x?

Answer 3

Yeah, we don't ever write 1x, just x.

When it's just x it means it really is 1x.

Is that helpful?

Answer 4

yes thank you @pabloecortez07

Answer 5

No problem, ask me another question, glad to help.

Answer 6

This one's a bit more complicated, but same concept.

The basic formula is : y = mx + b

So let's try to get it in that form.

We can subtract 4x on both sides, that gives us:

6y = -4x + 12

We can divide by 6 on both sides to get y by itself.

y = -4/6x + 2

We are almost done, but we can still simplify -4/6, since that's really -2/3

So our final answer is:

y = -2/3x + 2

Did that help?
