Question

Will medal+fan PLEASE HELP!!
Can someone help and explain how to solve this question.
Write y=(-5/8)x+3 in standard form using integers.

Answer 1

@uri @nincompoop @Mehek14 @mathmale @pooja195

Answer 2

do you know what mean ,,standard form" of y ?

Answer 3

you need to know formula of ...

Answer 4

y=mx+c - yes ?

Answer 5

ya

Answer 6

how you can making integers from this fraction ?

Answer 7

I don't know

Answer 8

(y=mx+c) is NOT the standard form
that is known as the slope intercept form

'Standard' form is
Ax + By = C

start by multiplying both sides of equation by 8

Answer 9

ok but y 8?

Answer 10

to get rid of the fraction (-5/8)

that will produce an equation with just integers in it.

You then need to rearrange it into the form I wrote above:

Ax + By = C

Answer 11

oh okay so 8* y=(-5/8)x+3 *8= 8*y=(-5)x+3
right?

Answer 12

no - you didn't multiply properly

8y = 8(-5x/8 +3)

multiply ALL the terms in the brackets

Answer 13

3 isn't in the brackets tho

Answer 14

the right side of the equation is -5/8 x + 3

you need to multiply the whole of that by 8

so I put the brackets there to make it clearer

Answer 15

oh

Answer 16

i'm confused

Answer 17

so imultiply -5 and 3 by 8?

Answer 18

you started with

y = -5/8 x + 3

to get rid of the fraction you need to multiply the WHOLE equation by 8

so

8(y) = 8(-5/8 x +3)

so multiply the 8 into the brackets

Answer 19

so -5x+24

Answer 20

8y = -5x + 24

is the correct expansion

but to get to standard form you now need to ADD 5x to each side...

Answer 21

-5x or just 5x

Answer 22

Add 5x

that will get the constant term on its own on the right side...

Answer 23

ok so 8y+5x=-5x+3+5x
right?

Answer 24

no - you have copied wrong...
the left side is correct
(and then simplify the right side)

Answer 25

how?

Answer 26

first : you wrote 3 where there should be 24

8y +5x = 5x -5x +24

simplify that

Answer 27

8y+5x=5x+24?

Answer 28

8y +5x = (5x -5x) +24

simplify that

Answer 29

8y+5x=x+24

Answer 30

no

come on - look at the equation

we have done all this and you simply need to simplify it so it looks like

Ax+By = C

Answer 31

8y +5x = (5x -5x) +24


(hint - what is (5x-5x))

Answer 32

ok so iknow i've been so stupid and uve so paitent (thank you :) ) but i have another guess
8y+5x=1 i think

Answer 33

don't GUESS

that is not correct

hint what is 1-1 what is 2-2 what is 3-3 what is 5x-5x

Answer 34

ohhh its 0 x) i'm so stupid so 8y+5x=0

Answer 35

what happened to the +24?

Answer 36

8y+5x=24

Answer 37

That's correct - well done

so what we did was:

first get rid of the fraction by multiplying by the denominator

THEN arrange the equation by moving the x and y terms to one side, leaving the constant term(24) on the other

Answer 38

FINALLY thanks sooooo much :D
