Question

Will somebody help me and explain how to find the rate of change of 5x+3y=-2......PLEASE PLEASE PLEASE

Answer 1

Well, turn it into a y = mx + b equation first.

Answer 2

3y = -5x - 2
y = -5/3x - 2/3

Answer 3

ok

Answer 4

so in the second equation, whih one is the slope?

Answer 5

-5/3?

Answer 6

yes.

Answer 7

so the slope is the same thing as the rate of change. so there's your answer :)

Answer 8

O MY GOSH THANK YOU SO MUCH.... but one more question?

Answer 9

sure.

Answer 10

on graphs would the rate of change be the slope as well?

Answer 11

yes.

Answer 12

ok thank you

Answer 13

using a graph, if you don't know the slope formula, use this: slope is rise over run. so on the graph of the line, find an point where both x and y values are integers. Take a look at the rise (number of units up) and the run(number of horizontal units) to another integer point. tthe rise over the run would be the slope.

Answer 14

and you're welome, anytime :)
