Write the equation of the line f(3)=6 and f(8)=10
LuckyWell [14K]
F(x)=y
so
f(3)=6 and f(8)=10
the points are
(x,y)
(3,6)
(8,10)

y=mx+b
m=slope
b=yintercept

to find the slope between 2 points, (x1,y1) and (x2,y2)
the slope is (y2-y1)/(x2-x1)
(3,6)
(8,10)
slope=(10-6)/(8-3)=4/5

y=4/5x+b
find b


the equation for a line with slope m and a pointn on it is (x1,y1) is
y-y1=m(x-x1)

a point is (3,6)
y-6=4/5(x-3)
y-6=4/5x-12/5
add 6 or 30/5
y=4/5x+18/5

The total cost ,c, of renting a Canoe for n hours can be represented by a system of equations. Write the system of equations tha
Brut [27]

Answer:  \left \{ {{c=28} \atop {c=3n+13}} \right.

Step-by-step explanation:

<h3> The missing data is: " The cost of renting a conoe to use on River Y costs $28. The cost of renting a conoe to use on River Z costs $3 per hour plus a $13 deposit".</h3>

Let's find the first equation.

You know that the cost of renting a conoe to use on River Y costs $28. This is:

c=28

To find the second equation you need to remember the Slope-Intercept form of a Linear equation. This is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

Since the cost of renting a conoe to use on River Z costs $3 per hour plus a $13 deposit, you can identify that:

m=3\\b=13

Therefore,  the equation that represents this situation is:

c=3n+13

So, the System of equations that could be used to find the total cost "c" of renting a canoe for "n" hours, is:

\left \{ {{c=28} \atop {c=3n+13}} \right.
