Put these in the form y=mx+c as not sure how to do this? 6x5=2y 4x+2y=7 3y=4x+6 000 3x7=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) 6x5=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) 3x7=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.

You're using the wrong name for the form y=mx+b. That's called the SlopeIntercept form because it shows both the slope (m) and the yintercept (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) Quote:

This website is equipped with a $\LaTeX$ translator so that you can use the fancy math typesetting you see in Skeeter's post in this thread. You both may find it useful. See (http://www.docs.is.ed.ac.uk/skills/d.../37222014.pdf) Chapter 6 for the basics. as an example: $\displaystyle m = \frac{y_2  y_1}{x_2  x_1}$

Thank you I will fix that and be consistent.
