Answer:

<h2>-  \frac{ 1}{4}</h2>

Step-by-step explanation:

The line passes through points ( - 1 , 2 ) and ( 3 , 1 )

Let there points be A and B

A ( -1 , 2 ) -----> ( x1 , y1 )

B ( 3 , 1 ) -------> ( x2 , y2 )

Now, Let's find the gradient ( slope)

\frac{y2 - y1}{x2 - x1}

plug the values

=  \frac{1 - 2}{3 - ( - 1)}

Calculate the difference

=  \frac{ - 1}{3 - ( - 1)}

When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression

=  \frac{ - 1}{3 + 1}

Add the numbers

=  \frac{ - 1}{4}

Use \frac{ - a}{b}  =  \frac{a}{ - b}  =  -  \frac{a}{b} , to rewrite the fraction

=  -  \frac{1}{4}

Hope this helps...

Best regards!!

How would you teach something you have learned this year in Math to someone younger than you? Write more than 5 sentences
rewona [7]

Answer:

ok here ya go

Step-by-step explanation:

A way that I would teach someone something that I learned in math this year to someone else is simple. I would start by writing everything out so that they have a visual of what I am teaching them. I would also use a visual of a real world situation so that it relates to something they would understand. Teaching someone younger than you means they probably will not understand as easy as you understood it so, I would be very slow and make sure if they are confused to help them. I would also make sure not to be too bossy, understanding that they may not understand and that is ok.

Herman is traveling 125 miles from his house to the beach by car. Herman plans to stop for lunch when the ratio of the distance
aliya0001 [1]

Answer:

250 miles

Step-by-step explanation:

The given distance between the house and the beach is 125 miles.

Let x miles be the distance between the house and the lunch stop.

So, at the time of the lunch stop, he already traveled x miles, the remaining distance is the distance between the lunch stop and the beach.

Let y miles be the remaining distance, so

y=125-x.

Give that the ratio of the distance he has traveled, x, to the distance he still has to travel, y, is 2:3,i.e

x:y=2:3

\Rightarrow \frac x y =\frac 2 3

\Rightarrow \frac {x}{125-x}=\frac 2 3

\Rightarrow 3\times x=2\times(125-x)

\Rightarrow 3\times x=2\times125-2\timesx

\Rightarrow 3 x=250-2x

\Rightarrow 3x-2x=250

\Rightarrow x=250

Hence, the distance traveled by Herman when he stops for lunch is 250 miles.
