(5,12)and (2,6) rate of change?
initial value?
hurry i need this done.

Part 1) The rate of change is

Part 2) The initial value is

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

where

m is the slope or rate of change

b is the y-intercept or initial value

step 1

Find the slope or rate of change

The formula to calculate the slope between two points is equal to

we have the points

(5,12)and (2,6)

substitute the values in the formula

therefore

The rate of change is

step 2

Find the initial value

we have

substitute in the equation

solve for b

---> initial value

The linear equation is equal to

The y-intercept or initial value is 2

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
