Question

Write the given equation in slope-intercept form, y = mx + b, by solving for y:
4x – 2y = 10
Answer

y = 2x – 5

y = 2x + 5

y = -2x – 5

y = -2x + 5

The point (3, 0) is a solution of the equation: y = 2x − 11
Answer True False

Answer 1

@aegidious

Answer 2

u good at math?

Answer 3

yeah, okay first you want to isolate the y value

so to do that, you subtract the x value from both sides to get it onto the other side

4x-2y=10
-4x -4x

-2y=10-4x

Answer 4

make sense so far?

Answer 5

ok yeah

Answer 6

then you divide everything by -2 to get y all by itself

Answer 7

ok i dont get it :/

Answer 8

you need to get y=mx+b, right?
well we have -2y=-4x+10

Answer 9

we need to get that -2 off of the y, okay? that way y is all by itself

Answer 10

oh ok now i get it

Answer 11

so what answer did you get?

Answer 12

is the answer (c) ?

Answer 13

the 3rd one down? you don't have them lettered in the question so I don't know which is C

Answer 14

is this the answer y = -2x – 5

Answer 15

the third one

Answer 16

you forget that when you're dividing negatives, they become positive. -4x is a negative divided by a negative -2

Answer 17

try again

Answer 18

so if they become positive numbers then i think the answer is y=2x+5

Answer 19

mmmm the negative -4x becomes a positive 2x, yes
BUT a positive divided by a negative becomes negative. The positive 10 divided by a negative then becomes.......what? ;)

Answer 20

u know it would be very nice if u would just give me the answer:]

Answer 21

ok the answer has to be y=2x-5 right....

Answer 22

YES! :)

Answer 23

lol ty so u gonna help me with the second Q?

Answer 24

and then for the second one, all you do is plug 3 into the x value. If you calculate your y as being 0, then the answer is true. If you get any other number for y, then it's false

Answer 25

the answer is -5 so is it false?

Answer 26

Exactly :)

Answer 27

yay -pats myself on the back- :]

Answer 28

Calculate the slope of the points (-2, -1) and (3, 4).

wb this Q

Answer 29

give a medal if you like my help ;)

Answer 30

ok but if u just leave after i give it to u im gonna end ur life :]

Answer 31

come at me bro!!! XD

Answer 32

lolol okay, do you know rise over run?

Answer 33

oh trust me i will

Answer 34

did just gimmi the answer and i'll fan u

Answer 35

the slope is 1

Answer 36

good boy :]

Answer 37

Solve the following system of linear equations.

3x + 2y = 10
2x + 3y = 15/2
Answer

No solution

y = (-3/2)x + 5

x = 3, y = -1/2

x = 3, y = 1/2<----this is my answer

Answer 38

is it correct?

Answer 39

nuh huh, can only do so much ;) If you want my help, open another question XD

Answer 40

i hate u ok give me a second
