Question

what is the rate of change of 5x + 3y = -2

Answer 1

well..... first you put all the x's on one side and make y by itself... which should turn out to be... \[y=\frac{-2-5x}{3}\]

Answer 2

or \[y=-\frac{2}{3} - \frac{5x}{3}\]

Answer 3

then just take the derivative of that....

Answer 4

so would it be 7x/3??

Answer 5

not really..... have you learned derivatives?

Answer 6

no

Answer 7

o great.... why do they try to teach rate of change without derivatives??? either way.... basically you would bring down the exponent of the x for each part of the equation.... so in this case... the rate of change (which we will denotate as dy) will be...
\[dy=-\frac{5}{3}\]

Answer 8

ok thank you very much i actually understand it, :-)

Answer 9

lol anytime XD
