Question

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

Ok so this is simple. the equation is
y = mx + b
m being slope and b being the y-intercept
do you understand so far??

Answer 2

( the y-intercept is when -- on a graph -- the line that connects the points going through the y-axis. Heres an example..)

Answer 3

this would be the y-intercept

Answer 4

Since we already know the slope (2), we can place that into the sport where m was
so it was y = mx + b
but now its y = 2x + b

Answer 5

The next step is replacing b with an actual number.so using the coordinates (3,4), we can easily find the y-intercept (b).

Answer 6

How do we find it?

Answer 7

XD haha! Ok so do you know what the y-intercept is??

Answer 8

or do you know what the meaning is??

Answer 9

yup

Answer 10

i know what y- intercept is :)

Answer 11

ok so you know that the full point slope equation is y = mx +b right?

Answer 12

yea

Answer 13

So youre just having trouble identifying where to place the numbers?

Answer 14

yup

Answer 15

Ok so in the equation y = mx + b, m is the slope. So using the information you gave me, i know that the slope is 2. so now the equation is...

Answer 16

(Youre turn XD)

Answer 17

let me seee

Answer 18

wait what is the answer tho?

Answer 19

Well OpenStudy doesn't really like when people give out answers. Walking you through it will only take a second with cooperation :)

Answer 20

All you have to do is find the y intercept which is very easy

Answer 21

okay :)

Answer 22

So we know the slope, yeah? Its two. The variable m, is representing slope... so what is the equation now...?
