Question

please help me
in the graph of a line, the ratio for the slope indicates the rate of change

find the rate of change for each table, equation, or graph. how did you find the rate of change?
a. x 2 4 6 b. 5x+3y=-2
y 10 20 30
c. its a graph all draw it

Answer 1

you want to find how fast or slow y is changing as x changes, right ?
so you need find the ratio of (y2-y1)/(x2-x1)

a. 5
b. -5/3
c. ur graph is not clear. apply above formula.

is it clear... how slope and rate of change are same ?

Answer 2

a. x 2 4 6
y 10 20 30
sorry dont know why that happend this should of been a

Answer 3

Answer 4

ya all do the graph my self thanks

Answer 6
