Put these in the form y=mx+c as not sure how to do this?

6x-5=2y 4x+2y=7 3y=4x+6 000

3x-7=6y 3x+3y=6 7y+6x=60 000

Many thanks xx

$ax + by = c$

$by = -ax + c$

$y = -\dfrac{a}{b} x + \dfrac{c}{b}$

Hello Desagni, this was what I found for the 6 equations and turned it into slope formula.
1) 6x-5=2y slope formula is: Y=3x-(5/2)
2) 4x+2y=7 slope formula is: Y=-2x + 7/2
3) 3y=4x+6 slope formula is: Y= (4/3)x +2
4) 3x-7=6y slope formula is: Y= (1/2)x-(7/6)
5) 3x+3y=6 slope formula is: Y= -x+2
6) 7y+6x=60 slope formula is: Y= (-6/7)x + (60/7)

The idea Desagni is rearranging the equation to fit the slope formula which is y=mx+b.
This should help. Let me know if you have any questions.

Hi. Actually, the idea is to solve the given equations for y. That doesn't require using the slope formula.

You're using the wrong name for the form y=mx+b. That's called the Slope-Intercept form because it shows both the slope (m) and the y-intercept (0,b).

Here is the Slope Formula; we use it to calculate the slope when we have coordinates of two points on the line (x1,y1) and (x2,y2).

m = (y2 - y1)/(x2 - x1)


1) 6x-5=2y slope formula is: Y=3x-(5/2)
2) 4x+2y=7 slope formula is: Y=-2x + 7/2
3) 3y=4x+6 slope formula is: Y= (4/3)x +2
4) 3x-7=6y slope formula is: Y= (1/2)x-(7/6)
Here's a couple notes about notation, Ninja. We don't need grouping symbols around some values of b. Technically, it's not wrong to type them, but they don't really do anything, above. However, it is good form to not switch back and forth between using symbols Y and y. Those are different symbols, in math, so pick one or the other and use it consistently. Cheers

:cool:

Thank you I will fix that and be consistent.
