Question

Find the rate of change with equation 5x + 3y = -2

Answer 1

ok, I;m just confused where to start.

Answer 2

first find y =mx+b
then
m= delta y / delta x

Answer 3

So am I solving for Y?

Answer 4

\[5x + 3y = -2 \\3y =-5x-2 \\\\y=\frac{ 1 }{3}(-5x-2)\\y=\frac{ -5x }{3}+\frac{ -2 }{3}\\ \frac{ \Delta y }{ \Delta x } =\frac{ f(x+ \Delta x)-f(x) }{ x+\Delta x -x }=\frac{ -5 }{ 3 }\]

Answer 5

Ok, I did the first and second parts like you did.
Just wondering why the 3rd part changes to a +. Is it because of the function?

Answer 6

yes line is a function
like y=f(x)

Answer 7

Ok, thank so much!
