What is the equation of this line?

Answer 1

Answer 2

@TheSmartOne

Answer 3

ok, first let's find the slope :)

Answer 4

3x / 1y ?

Answer 5

\(\sf\Large Slope = \frac{\color{blue}{y_2}-\color{red}{y_1}}{\color{green}{x_2}-\color{purple}{x_1}}\)

Where the two points are in the form:

\(\sf\Large (\color{purple}{x_1},\color{red}{y_1})~and~(\color{green}{x_2},\color{blue}{y_2})\)

Answer 6

what is that?

Answer 7

ohh nvm, its 3, -1 and 6,1

Answer 8

the point is (3,0) and (6,1)

Answer 9

so, what would the slope be? :)

Answer 10

1/3

Answer 11

3/1 or 1/3

Answer 12

now, what is the y-intercept?

look for where x = 0, and y crosses the y-axis

Answer 13

y-intersept = -1?

Answer 14

correct! :D

Answer 15

:D

Answer 16

so now we plug it into the slope-intercept form :)

y = mx + b

we got m = 1/3

and b = -1

Answer 17

ok

Answer 18

so what do you get? :)

Answer 19

1/3*6+-1 = 1?

Answer 20

not sure where the y and x ran away

we have to keep y and x

and only replace m and b

y = mx + b

m = 1/3

substitute that in and we get:

y = (1/3)x + b

b = -1

plug that in :)

Answer 21

ok so its y = (1/3)x + -1? for the answer?

Answer 22

almost there :P

Answer 23

1/3(x) + (-1) = (1/3)x - 1

so your final answer is y = (1/3)x - 1

Answer 24

ok, thanks :)

Answer 25

Anytime! :D
