i need to know how to solve y=mx+b when the teacher explains it, it seems really easy but i cant do it on my own and i have a test tomorrow.... PLEASE HELP!!!!
say 2x=3y=21 how would u solve it?

hey its not at all that tought yaar
okay, the best possible way is to first think abt the person whom u love the most n then think that solving this question is going to make him or her happy. then ,m if u really luv that perosn, then , u would surely do that.
look, if u say that 2x=3y=21
thn, its simple
2x=21, i.e x=21/2 or 10.5
3y=21 i.e. y =21/3= 7
x=10.5 and y=7
still any probs

well, y is the y point in a pair or coordinates...the 4 in the (4,5). M is the slope, and b is the y intercept. if 2x=3y=21, x=10.5 and y=7. You would have to have another point, but when you have the other point, you find the slope and then plug the numbers into the y=mx+b equation to find b.

since 2x=3y=21 we will split it into two:
first part:
2x=21 (divide both by 2)
x=10.5
second part:
3y=21 (divide both by 3)
y=7
easy..

you've written each little thing you want for the answer. ;) y = ok*x + b ok = (y1 - y2) / (x1 - x2) = (3 + a million) / (2 + 2) = 4 / 4 = a million So the equation is y = x + b. b is an arbitrary parameter, that takes values from -inf to +inf, (there are infinitely many strains that are parallel to a supply one). you could determite the fee of b on condition that you've some extra constraints - case in factor, the purpose (a million,2) belongs to the line.

2x=3y=21
2x=21>>>>x=10.5
3y=21>>>>y=7
