The equation a line that has a slope of -4 and goes through point (1,-5) in slope intercept form is y = -4x - 1

<h3><u>Solution:</u></h3>

Given that line that has a slope of -4 and goes through point (1,-5)

We have to write the equation of line

<em><u>The slope intercept form is given as:</u></em>

y = mx + c ------- eqn 1

where "m" is the slope of line and "c" is the y - intercept

Substitute slope "m" = -4 and (x, y) = (1, -5) in eqn 1

-5 = -4(1) + c

-5 = -4 + c

c = -5 + 4 = -1

<em><u>Substitute c = -1 and m = -4 in eqn 1</u></em>

y = -4x - 1

Thus the required equation of line is found

Answer:

(a) 0.107 million per year

(b) 0.114 million per year

Step-by-step explanation:

$A(t) = 11.19(1.009)^t$

(a) The average rate of change between 2000 and 2014 is determined by dividing the difference in the populations in the two years by the number of years. In the year 2000, $t=0$ and in 2014, $t=14$ . Mathematically,

$\text{Rate}=\dfrac{A(2014) - A(2000)}{2014-2000}=\dfrac{11.19(1.009)^14-11.19(1.009)^0} {14}$

$A(0)=\dfrac{12.69-11.19}{14}=\dfrac{1.5}{14}=0.107$

(b) The instantaneous rate of change is determined by finding the differential derivative at that year.

The result of differentiating functions of the firm $y=a^x$ (where $a$ is a constant) is $\dfrac{dy}{dx}=a^x\ln a$ . Let's use in this in finding the derivative of $A(t)$ .
