Question

What is the equation of the line that has a slope of 3 and goes through point (4, 7)?

Answer 1

\[\huge~\rm~y-y_1=m(x-x_1)\]
Use this it is the Point-slope formula
Substitute the follwing values into the formula
m=slope so 3
4=x1
7=y1
(x1,y1)

Answer 2

y-7=3(x-4)
is that all?

Answer 3

Do they want slope -intercept form?

Answer 4

it just says write an equation, it doesn't specify what type.

Answer 5

hmm @Loser66 @perl

Answer 6

just simplify more

Answer 7

So slope intercept form....
y-7=3(x-4)
\[\huge~\rm3(x-4) \]
distribute that

Answer 8

y-7=3x-12
y=3x+19
I have no idea if i did that right

Answer 9

\[\huge~\rm~3 \times-4=??\]

Answer 10

OH right y=3x+5?

Answer 11

not quite :( answer my question because that will get you the right answer u are very close

Answer 12

-4 x 3 =?

Answer 13

-12

Answer 14

good
y-7=3x-12
Ok now finish it off :)

Answer 15

y=3x-5?

Answer 16

yes :)

Answer 17

Good job ^_^
