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

Question

anonymous · Answer

Rate of change= slope. 
Get it into point slope form. y=mx+b, where m is the slope.

anonymous · Answer

change into linear form of y = mx + b, and you'll get y = -5/3 - 2/3 so the m is the slope or the rate of change is -5/3

anonymous · Answer

missed the x it's supposed to be y = -5/3x - 2/3

anonymous · Answer

The coefficient on x is the slope.

anonymous · Answer

Rate Of Change :
5x+3y=-2 subtract 5x from both sides
 
5x-5x + 3y = -2 -5x
 
3y = -5x - 2 Divide both sides by 3
 
3y/3 = (-5x - 2)/3
 
y = -5/3x - 2/3

anonymous · Answer

mk. I'm still a little confused though. Why is the answer  y = -5/3x - 2/3?

anonymous · Answer

It's the point slope form of the equation y = m (slope or rate of change) x + b (y-intercept)

anonymous · Answer

alright. thanks.

anonymous · Answer

You have to solve the equation for Y and you'll get the point slope form...
