Question

Please help!



3. Solve: (y - -3) = -1/2 * (x - 4)

-show work please-

Answer 1

what are you trying to say?

Answer 2

what do you mean? @Wolfboy

Answer 3

that was at @iambatman

Answer 4

XD mwahahaha anyway back to the problem is it solve or spimplify

Answer 5

solve it, . like my teacher gave us the answer but, we have to show how she got that answer, the problem is : Which equation represents a line with slope - 1/2 that passes through (-3, 4) ?
And the answer is : 2y + x = 5

now i need to show work on how she got that.

Answer 6

well you could graph it.

Answer 7

Start at (-3,4) and use the slope to find the x and y intercept.

Answer 8

I believe that could be a helpful start

Answer 9

im having a brain fart can someone help? @iambatman @nincompoop

Answer 10

Which question?

Answer 11

Solve: (y - -3) = -1/2 * (x - 4)?

Answer 12

second one apparently

Answer 13

"Which equation represents a line with slope - 1/2 that passes through (-3, 4) ?
And the answer is : 2y + x = 5

now i need to show work on how she got that"

Answer 14

So you have slope and the x, y coordinates, just plug it in?

Answer 15

y=mx+b

Answer 16

yea but the final answer is not in that form apparently so im confused

Answer 17

thats what i was thinking to

Answer 18

Okay @Mclovin21, I see you got very close to the correct answer.

Answer 19

Ok so we have slope, m = -1/2, and you have coordinates (x,y) = (-3, 4).
We want it in y = mx+b form
4=-1/2(-3)+b

solve for b, then put it all together.

Answer 20

Good, now multiply 2 both sides. And please:

Please help!



3. Solve: \((y - \color{red}(-3\color{red})) = -1/2 * (x - 4)\)

Answer 21

Do not forget to add those brackets.

Answer 22

ok so i guess i was thinking correctly @iambatman thanks for clarifying

Answer 23

Np

Answer 24

Now can you tell me @Mclovin21 , what will you get by multiplying 2 both sides.

Answer 25

umm 3 ?

Answer 26

@iambatman and @Wolfboy , you can also use this equation:

\((y-y_1) = m(x-x_1)\)

where m is the slope and \((x_1,y_1)\) is the point lying on the line.

@Mclovin21 , no let me show you.

Answer 27

Yes, I know of the point - slope form, but I thought it was easier if we explained it this way, since wolf was already doing it.

Answer 28

yea I thought since it was the most simple it was the best route to take
