Question
Given the slope and y-intercept can you write an equation for the line?
Solution 1
Y=mx+b
m=slope
b=yintercept

example
if slope=3
yintercept is 2 then
y=3x+2
simple as that
Solution 2
Yes, because the equation to find the proportional relationship is y=kx. Y- origin
K- constant rate of proportionality
Question
HELP ME PLEASE What can you tell about the initial value and the y-intercept?
Solution 1
The y intercept is when x=0
x is the depdendent numer
when x=0 (or when no change has occured), the y intercept is te starting value

example
a car is at the 1 mile mark
if it goes 10 miles per hour, what mark will it be at in 10 minutes
distance=10x+1
1 is starting point, when x=0, or when the car hasn't traveld at all

yint is the initial value of the function
Solution 2
Well, the slope is 8 and the y-intercept is -10
the slope is always the number in front of just 'x' and the y- intercept is any number without a variable (Thats all I got) Hope this helps!

Question
Factor the expression. 15n−18
Solution 1
I saw that you put this question here twice so here's my answer again with the math.

Factor 15n−18
15n−18
=3(5n−6)

3(5n−6)

5n-18 factored is
3(5n−6)
Solution 2
Divide each term by 3...
15n - 8 = 3(5n - 6)

Question
Factor the expression. 15n−18
Solution 1

For this case we have the following expression: We look for the factors of each coefficient.

We have then: Taking the biggest common factor we have: Therefore, the factored expression is given by: the factored expression is given by: Solution 2
Factor 15n−18
15n−18
=3(5n−6)

3(5n−6)

5n-18 factored is
3(5n−6)
Question
A coyote can run up to 43 miles per hour while a rabbit can run up to 35 miles per hour.write two equivalent expression and then find how many more miles a coyote can run in six hours than a rabbit at these rates
Solution 1
D=s*t
distaance=speed times time

cd=coyote distance*time=ds*dt
rd=rabbit diatance*time=rs*rt

given
t=6 for all, so dt=rt=6

and ds=43
rs=35

cd=43*6=258miles
rd=35*6=210miles

how much more?
258-210=48

48 more miles

Question
Herman horse trader bought a horse for \$600 and then sold it for \$700. The next day he bought it back for \$800 and then sold it for \$900. How much money did Herman make altogether?
Solution 1

The total amount of the profit will be \$200.

### What is a profit?

A monetary profit, particularly the distinction between the amount gained and the actual cost of purchasing, running, or creating anything.

The profit is given as,

Profit = Selling price - Cost price

Herman horse trader bought a horse for \$600 and then sold it for \$700.

Then the profit will be

⇒ \$700 - \$600

⇒ \$100

The next day he bought it back for \$800 and then sold it for \$900.

Then the profit will be

⇒ \$900 - \$800

⇒ \$100

Then the total amount of the profit will be

P = \$100 + \$100

P = \$200

The total amount of the profit will be \$200.

More about the profit is given below.
