Question

**Will Medal**
What is the slope-intercept form of the function that contains the point (3, 4) and has a slope of 2?

y = ? x + ?

Answer 1

I need help ASAP plzzz!!!!!!!!!!!!!!!!!!

Answer 2

Our slope-intercept form of a line is given by:\[\Large\rm y=mx+b\]Do you know which letter corresponds to the slope?

Answer 3

Woops I clicked the wrong question >.< lol
Sorry sorry.

Answer 4

Anyway, y=mx+b.

m is our slope.

Answer 5

Ok

Answer 6

Giving us,\[\Large\rm y=2x+b\]

Answer 7

To find the y-intercept, \(\Large\rm b\), we need to plug in the point that they gave us,\[\Large\rm 4=2(3)+b\]And then solve for b.
Do you understand how I plugged that coordinate in?
Solve for b! What do you get? :)

Answer 8

So I would multiply 2 and which gives me 6?

Answer 9

2 and 3 my bad

Answer 10

mhm, then we need to isolate the b somehow.
Hmm, the 6 is being `added` to the b.
To isolate the b, we want to perform the inverse to move the 6 to the other side.
Inverse of addition? :o

Answer 11

Um not sure how to do that

Answer 12

Subtraction is the opposite of addition, yes?
So we'll subtract 6 from each side to get the b alone.

Answer 13

Ok which comes out to 6b or b6

Answer 14

6b? Oh boy :( Not sure where that's coming from.
