Answer:

y = -4x -8

Step-by-step explanation:

The slope is given by

m = (y2-y1)/(x2-x1)

m = (0--4)/(-2--1)

= (0+4)/(-2+1)

=4/-1

= -4

We know the point slope form of a line is

y-y1 = m(x-x1)

y-0 = -4( x--2)

y = -4(x+2)

y = -4x -8

Can you find the rate of change for the following function: -6x + 3y =9?

IgorC [24]

Answer:

The general rate of change can be found by using the difference quotient formula. To find the average rate of change over an interval, enter a function with an interval:

f ( x ) = x ^2 , [ 2 , 3 ]

The rate of Change is 2
