What is the slope of the line with equation y = –3? I have no idea how to do this.

Sure you do !
I'll tell you what it is, and why, and you'll slap your forehead
and call yourself names.

The 'standard' form of an equation that shows the slope and intercept is

y = (slope) x + (intercept)

<em><u>What if the slope is zero</u> ?</em>

Then the equation is y = (0) x + intercept
or
y = intercept.

Does that look anything like y = -3 ?

#a

H(0)

It refers to y value on graph when x is 0

So here it refers to y intercept

y intercept (0,5)

Hence

H(0)=5

#b

Observe the graph

y intercept is not 0 so it's not true

#3

Domain is set of x values in graph

#4

Range is set of y values on graph

Please help!! With step by step

Answer:

$R=\$145.12$

Step-by-step explanation:

<u>Compound Interest</u>

This is a well-know problem were we want to calculate the regular payment R needed to pay a principal P in n periods with a known rate of interest i.

The present value PV or the principal can be calculated with

$P=F_a\cdot R$

Solving for R

$\displaystyle R=\frac{P}{F_a}$

Where Fa is computed by

$\displaystyle F_a=\frac{1-(1+i)^{-n}}{i}$

We'll use the provided values but we need to convert them first to monthly payments

$i=7\%=7/(12\cdot 100)=0.00583$

$n=3*12=36$

$\displaystyle F_a=\frac{1-(1+0.00583)^{-36}}{0.00583}$

$F_a=32.386$

Thus, each payment is

$\displaystyle R=\frac{4,700}{32.386}=145.12$

$\boxed{R=\$145.12}$
