Question

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

y = 2 x +?

Answer 1

plug in the ordered pair

Answer 2

@iambatman

Answer 3

?

Answer 4

plug in 3 for x and 4 for y

Answer 5

substitute the equation with the ordered pair

Answer 6

ohh ok

Answer 7

so your equation becomes
4 = 2(3) + b

Answer 8

y=4x3?

Answer 9

no the slope stays the same
4 is in the y's place and 3 is in the x

Answer 10

oh ok

Answer 11

like this
4 = 2(3) + b

Answer 12

b is what you are looking for

Answer 13

y=2(3)+b

Answer 14

point slope form is
\[y-y _{1}=m(x-x _{1})\]

where m is the slope
(x1,y1)=(3,4)

Answer 15

@thebro55 no I showed you the equation looks like this:
4 = 2(3) + b

Answer 16

ok

Answer 17

now solve it

Answer 18

4=6?

Answer 19

4 = 6 + b
you need to isolate b

Answer 20

how?

Answer 21

move 6 to the other side

Answer 22

4=6+6

Answer 23

no you subtract 6 on both sides

Answer 24

2?

Answer 25

4 - 6 = 6 - 6 + b

Answer 26

-2=0

Answer 27

so b = -2

Answer 28

ohh. so the answer is: y=2x+-2?

Answer 29

@Mehek14

Answer 30

leave out the + sign
y = 2x - 2

Answer 31

thx
