Question

Given the equation y − 3 = one half(x + 6) in point-slope form, identify the equation of the same line in standard form.

x − 2y = −12
y = one halfx
y = one halfx + 6
y = one halfx + 9

I think that the answer is option 1, but I want someone else to check please :)

Answer 1

can you simplify the equation given to you?
y − 3 = one half(x + 6) is really
y − 3 = (1/2)(x + 6)

Answer 2

Wouldn't it be y = 1/2x + 6 simplified?

Answer 3

yep good job.
do you see which solution it is now?

Answer 4

Yeah I do now, but isn't standard form Ax + By = C

Answer 5

i'd give you another medal if I could. you are right again. can you get the simplified eqatuion into stanard form?

Answer 6

No, I don't think so

Answer 7

@DemolisionWolf

Answer 8

we have:
y = 1/2x + 6
move the 6 to the other side, and move the y to the other side

Answer 9

Would it be 6 = 1/2x + y?

Answer 10

-6 = (1/2)x - y
now times both sides by 2 to get rid of the fraction

Answer 11

Is it -12 = x - 2y?

Answer 12

you got it,
do you see the answer up there to pick it?

Answer 13

Answer 1?

Answer 14

yep ^_^

Answer 15

Thanks a lot!!!! :)

Answer 16

Can you check this one for me too? I think the answer is option 4, I want to be positive. :)

Given the equation y − 4 = three fourths(x + 8) in point-slope form, identify the equation of the same line in slope-intercept form.

−three fourthsx + y = 10
3x − 4y = −40
y = three fourthsx + 12
y = three fourthsx + 10

Answer 17

option 4 is what I come up with also ^_^
